The low-power characteristics of the product can be used in environmental monitoring equipment with high sensitivity, The intelligent algorithm calculates the TVOC /eco2 value and outputs the I2C signal, which can communicate directly with the single chip microcomputer. the metal oxide (MOX) sensor for detecting indoor air quality integrates 8-bit MCU for computing the first level algorithm, 12 bit ADC for sensor reading and digital conversion, and I2C slave can be directly connected to the reset /interrupt control of the main control system. Working voltage: 1.8 - 3.6V (3.3V recommended) Recommended operating temperature:-5°C-+50 °C Storage temperature:-40 °C- + 125 °C Equivalent CO2 (eco2) Detection range: 400ppm - 5000ppm Communication interface: I2C interface Supported 12C bus frequencies:10kHz - 400kHz (100kHz recommended) Color: As Shown Material: PCB Package Contents: 1 x Gas Sensor Module Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
