Seeed 101020001 Grove - HCHO Sensor

Seeed 101020001 Grove - HCHO Sensor is a semiconductor VOC gas sensor. It uses the VOC sensor WSP2110 whose conductivity changes with the concentration of VOC gas in the air. With a circuit, the conductivity can be converted to an output signal that corresponds to the gas concentration. This sensor has very high sensitivity and stability, that can detect gas whose concentration is up to 1ppm. It can be used to detect Toluene, Methanal, Benzene, Alcohol, Acetone and can detect the presence of harmful gas in the home environment, which makes it a good assistant to improve indoor air quality.

* Up to 1ppm high sensibility: High sensitivity to organic gases such as toluene, benzene, methanal * Quick response and resume: Real-time detection of gas values * Good stability and long life: The sensor value fluctuates little * Simple detection circuit: The higher the concentration of gas is, the higher conductivity of sensor gets * Grove compatible interface: The product ensures "Plug and Play" and could be versatile for various applications of Grove * Operating Voltage: 5.0V ± 0.3V * Chip: WSP2110 * Detection Gas: toluene, methanal, benzene, alcohol, acetone & etc. * Detection range: 1～50ppm * Sensor Resistance Value(Rs) 10KΩ-100KΩ(in 10ppm HCHO) * Sensitivity: Rs(in air)/Rs(10ppm HCHO)≥5
