The Gas Sensor Board is designed to work in conjunction with one of the gas sensors listed below (not included) allowing you to determine when a preset gas level has been reached or exceeded.

• CO (Carbon Monoxide) Gas Sensor
• CH4 (Methane) Gas Sensor
• LPG (Propane) Gas Sensor
• C2H5OH (Alcohol) Gas Sensor

The gas sensor simply plugs into the Gas Sensor Board, making it easy to use these sensors in embedded projects. The board can interface to a microcontroller with only two I/O pins, allowing the sensor to be controlled and monitored automatically.

Key Features:

• SIP header interface with 0.1" spacing for easy connection to prototyping boards or extension cables  
• Controllable internal heater facilitates accurate measurements  
• Low-power standby mode reduces power usage for embedded projects
• Only two microcontroller I/O pins required for operation
• Voltage requirements: 5 VDC
• Current requirements: ~165mA (heater on), ~60mA (heater off)
• Interface: 1 TTL compatible input (HSW); 1 TTL compatible output (ALR)
• Dimensions: 1.50 x 1.0 x 1.0 in (38.1 x 25.4 x 25.4 mm)
• Operating temp range: 14 to 122 °F (-10 to +50°C)

Application Ideas:

• Gas level over-limit alarm
• Stand-alone/background sensing device
• Environmental monitoring equipment
