This little guy will measure both pressure and temperature throughout your entire flight. It lacks the ability to read humidity, though, so if you're looking for that too, go with the BME280 instead. This precision sensor is the best low-cost sensing solution for measuring barometric pressure and temperature. Because pressure changes with altitude you can also use it as an altimeter. The sensor is soldered onto a PCB with a 3.3V regulator, I2C level shifter and pull-up resistors on the I2C pins. Using the sensor is easy. If you're using an Arduino, simply connect the VIN pin to the 5V voltage pin, GND to ground, SCL to I2C Clock (Analog 5) and SDA to I2C Data (Analog 4). Download the BMP180 Arduino library and example code for temperature, pressure and altitude calculation. Immediately you'll have precision temperature, pressure and altitude data.
This is a bit of a hack that we've put together on our flights. This product is intended to be used with LiPo batteries to measure the voltage and begin sounding an alarm when the voltage reaches a low voltage threshold that you define. We use it a bit differently. Our flight computer connects power to ONLY pin #2 on this product. When power is supplied to only PIN #2, the audible alarm will begin sounding right away and continue until power is lost. This is what we use as a reliable landing alarm as well as a locator beacon to help us find the payload after landing. It's easy and very reliable. Simply apply power to PIN #2 and you have a long lasting beeping alarm to help you find the payload.

These amazing power boosters will take a voltage as low as 1.8V and output a clean 5V power supply. We use these quite frequently. Particularly, we use a single 3.7V 18650 battery and run the power through a power boost and then the 5V power out to our action cameras. Additional pins allow you to programmatically turn on/off the output power and receive low battery signals.
- Synchronous operation means you can disconnect the output completely by connecting the ENable pin to ground. This will completely turn off the output
- 4A internal switch means you can get 1000mA+ from as low as 1.8V, 1500mA+ from 2 NiMH or Alkaline batteries, and at least 2000mA from a 3.7V LiPoly/LiIon battery or 3 NiMH/Alkalines. Just make sure your batteries can actually supply the required 2-4A, OK?
- Low battery indicator LED lights up red when the voltage dips below 3.2V, optimized for the most common usage of LiPo/LiIon battery usage
- On-board 1000mA charge-rate 'Apple/iOS' data resistors. Solder in the included USB connector and you can plug in any iPhone or iPod for a speedy 1000mA charge rate. Works with iPads, both mini and 'classic' type.
- Full breakout for battery in, control pins and power out 90%+ operating efficiency in most cases (see datasheet for efficiency graphs), and low quiescent current: 5mA when enabled and power LED is on, 20uA when disabled (power and low batt LED are off)
This data logging shield is designed for the Arduino platform and is utilized on our main OLHZN flight computers to save sensor and other telemetry data in 1 second increments to an on-board SD card.
- On board Real time clock (RTC) keeps the time going even when the Arduino is unplugged. Note: The RTC requires a small coin cell battery (not included). The board will still operate without the coin cell battery. Once installed the RTC battery will last for years.
- Adafruit libraries and example code for both SD and RTC mean you can get going quickly
- Prototyping area for soldering connectors, circuitry or sensors

This GPS breakout board module is utilized on all the OLHZN high altitude weather balloon flights. It will register altitude and positioning reports up to 160,000 FT (48,768 m), but you must be sure to enable "Flight Mode" (Mode 7) via software on startup. The active antenna is a must have if you're utilizing an on-board action camera. The active antenna will ensure that electromagnetic interference from the action camera(s) will not disrupt the GPS signal reception.
- Micro USB port allows you to connect the GPS module to your computer without USB-TTL cables.
- The GPS module also has a ceramic passive antenna so you can utilize the module without the external antenna, if desired.
- The SMA port allows you to conveniently connect the 3m Active Antenna for a much stronger satellite connection.
- The TTL port (header pins) allow you to conveniently connect this module to an external single chip microcomputer.
These are the cameras we use on OLHZN flights with camera footage. They are inexpensive while still having great quality video. We use the cameras in "Dashcam mode" so that once power is applied to the camera, it automatically starts recording. This allows us to have the camera mounted ahead of time and just turn on the power to launch. We also set the recording to be a fixed 5 minute video file to ensure if something happens to the camera, we still retain most of the footage.

We have not used these cameras ourselves, but they appear to be near replicas of the Lightdow LD4000 cameras that we fly onboard our OLHZN flights. They are relatively inexpensive and we would expect them to provide decent video quality. We use our cameras in “Dashcam mode” so that once power is applied to the camera, it automatically starts recording. This allows us to have the camera mounted ahead of time and just turn on the power to launch. We also set the recording to be a fixed 5 minute video file to ensure if something happens to the camera, we still retain most of the footage.

Our main flight computer is based around the Arduino Mega platform. It is a very reliable platform and works well for logging telemetry and broadcasting positioning reports via APRS over amateur radio frequencies. When purchasing any Arduino product, be sure the Arduino is genuine and not a fake, replica or counterfeit device. Fake and replica Arduinos are generally not as reliable as they use cheaper parts, particularly when it comes to power regulation. For details on how to check if your Arduino is genuine see this Arduino page.
These are almost exactly the same camera as the Lightdow LD4000 cameras that we fly onboard our OLHZN flights. They are slightly upgraded and support up to 64 GB SD cards while still being relatively inexpensive and having great quality video. We use the cameras in “Dashcam mode” so that once power is applied to the camera, it automatically starts recording. This allows us to have the camera mounted ahead of time and just turn on the power to launch. We also set the recording to be a fixed 5 minute video file to ensure if something happens to the camera, we still retain most of the footage.

If you don't have an amateur radio license or want to have a backup system, the Spot 3 GPS Tracking System is a great option. It's not quite as good as having an amateur radio tracking system, but it comes in a close second place. The tracking system will generally stop operating above 60,000 FT., but will usually recover during the descent. The best setups will place this GPS tracking device in a gimbal so that no matter which way the payload lands, the GPS tracking unit always points up towards the sky to get the best reception. Note that this GPS tracking system requires an annual membership in addition to the device in order to get reception.

Experimental. These circuit boards are used by the OLHZN High Altitude Balloon team for high altitude weather balloon tracking. However, the circuit boards are considered experimental and may suffer from unforeseen errors or undiscovered technical deficiencies. An amateur radio license from the FCC is required to operate these in the United States and many other countries worldwide. Check your local governing body for details. Due to the experimental nature of these circuit boards, returns are not accepted on this product. The bare circuit board is the least expensive option, but you would need to purchase the assembly parts yourself. The source code, parts list and assembly instructions can be found at https://github.com/OverlookHorizon/OLHZN_Track If you want to have all the parts included or have the board pre-assembled for you, you may select those options too, if desired. They are not required, though. You can source the parts and build the entire board yourself for the lowest cost.
