This SensorBlock™ is capable of measuring air quality and temperature and has external connections for 2 digital inputs.
The Air Quality SensorBlock™ is perfect for environmental monitoring applications. The internal temperature and humidity sensors are accurate and can be used to measure temperature from -20 to +85 degrees C and air quality. The air quality sensing range is 450-2000ppm CO2 and 125-600 ppb TVOC equivilents . The external contact closure inputs can be used to monitor door openings, water leakage sensors, relay outputs from legacy equipment (such as pump run start), and more. Lastly, the analog input can be used to measure ratiometric sensors and voltage output sensors with a range of 0-2.5V.
An open collector output is provided that can sink up to 500mA at 50V. If the SensorBlock is powered externally, the output can be used to close relays, simulate switch closures, interface with alarm panels, and more.
