Discontinued. The LPG Gas Sensor, when used with our Gas Sensor Board (#27983), is designed to allow a microcontroller to determine when a preset propane gas level has been reached or exceeded. Interfacing with the sensor+board is done through a 4-pin SIP header and requires two I/O pins from the host microcontroller. This product combination is mainly intended to provide a means of comparing propane sources and being able to set an alarm limit when the source becomes excessive.
- Uses the MQ-5 LPG Gas Sensor
- Plugs into our Gas Sensor Board (#27983) for convenient prototyping
- Compatible with most microcontrollers
- Safety Devices (harmful gas detection)
- Environmental Monitoring
Precaution: Be aware that high concentrations of propane can be deadly. Always be careful to perform gas tests in well-ventilated areas. This LPG Gas Sensor Module in not designated for or approved for any application involving health or human safety. This LPG Gas Sensor Module is for experimental purposes only; Parallax Inc absolves itself of all liability and responsibility associated with the customer’s use of this LPG Sensor Module and is not responsible for any bodily injury, death, or property damage as a result of using this LPG Gas Sensor Module.
Note: This sensor, paired with our Gas Sensor Board (#27983), replaces our discontinued LPG (Propane) Gas Sensor Module (#27932). Please note that on boards labeled 27983 pin 2 is active-high, and on boards labeled 27904, 27930, 27931, and 27932, pin 2 is active-low.
