DFRobot (SEN0231) Formaldehyde Sensor, (HCHO)

Gravity formaldehyde (HCHO) sensor is an Arduino Raspberry Pi compatible modulewhich is the ideal solution for indoor air quality monitor. It can be used tomeasure HCHO in air. This sensor module is widely used in many air testingapplications, such as indoor air quality, real time quality monitoring stations.HCHO sensor module can detect and measure HCHO accurately. Many advantages areavailable, such as strong anti-jamming capability, high stability, ATC, highsensitivity (up to 0.01ppm) and long life (2 years in air). Integrated withGravity Interface which is easy to used, wide input voltage, and optional outputsignal, our module can be almost compatible with all MCU. According our samplecodes, an HCHO detector can be made very quickly. This is a formaldehyde (HCHO)sensor module with small size and Arduino compatibility.Features:- Accessory Type: Formaldehyde (HCHO) Sensor- For Use With: Arduino Raspberry Pi Development Boards- Product Range: Gravity Series- High stability and sensitivity, Automatic temperature compensation- Wide input voltage range from 3.3 to 6V, support DAC and UART output- Long life (2 years in air), high resolution (0.01ppm)- HCHO target gas, Alcohol and CO interference gas- 0 to 5ppm detection range, 0.01ppm resolution- Gravity-3 pin interface- Operating temperature range from 0 to 50 C- Dimension is 38mm x 28mm x 15mm/1.50 x 1.10 x 0.59inch, weight is 22g
