High Precision Digital Temperature and Humidity Sensor Measurement Module I2C Communication; The sensor outputs a calibrated digital signal in standard I 2C format.
The CJMCU-1100 is equipped with a newly designed ASIC-specific chip,an improved MEMS semiconductor capacitive humidity sensing element and a standard on-chip temperature sensing element.
Used for the detection of household environment and other air. Application and detection concentration range of kitchen equipment: qualitative inspection of 0~1000ppm gas. This product has high sensitivity and stability, and can detect gases above 0.1ppm.
Working voltage: DC 5V; Working current: 100mA; Output analog signal: 2.6-5V. The sensitivity can be adjusted, and you can set the sensor threshold. It can be directly connected to the microcontroller.
Note: This product is American standard and is designed for use in the United States. The socket and voltage vary from country to country. This product may require an adapter or converter to use in your region. For your experience, please check compatibility before purchasing.
Instructions for use: 1. Power supply voltage: +5V 2. AOUT: Analog output, voltage value change corresponding to gas quantity detected by chip, single chip can connect directly using ADC. 3. DOUT: Digital output is the result of comparing the output voltage values of AOUT and adjustable resistor, output semaphores 0 and 1. 4. Adjust the adjustable resistor of the module. When the output voltage of the adjustable resistor is less than AOUT, the output of DOUT is high level, while the LED lamp is on; On the contrary, DOUT output is low and the LED lamp is off. 5. Variable resistance value: 4K ohms 6. Voltage in clean air:
