LPG (Propane) Gas Sensor Module

The LPG (Propane) Gas Sensor Module is designed to allow a microcontroller to determine when a preset propane gas level has been reached or exceeded. Interfacing with the sensor module is done through a 4-pin SIP header and requires two I/O pins from the host microcontroller. The sensor module is mainly intended to provide a means of comparing propane sources and being able to set an alarm limit when the source becomes excessive.

Features:

Uses the MQ-5 LPG Gas Sensor

Easy SIP interface

Compatible with most microcontrollers

Application Ideas:

Sensing high propane gas concentration

Stand-alone / background sensing

Key Specifications:

Power requirements: 5 VDC @ ~175 mA (Sense Mode) / ~5 mA (Standby)

Interface: 1 TTL compatible input (HSW), 1 TTL compatible output (ALR)

Dimensions: 1.50 x 1.00 x 1.00 in (38.1 x 25.4 x 25.4 mm)

Operating temp range: +32°F to +158°F (0°C to +70°C)

Note: Parallax does not provide gas calibration data on the module and such data and alarm setting is the responsibility of the user to define. For information on user calibration please see the documentation.

Precautions: Be aware that high concentrations of propane can be deadly. Always be careful to perform gas tests in well-ventilated areas.
