Air quality monitor RK207D

The detector has built-in high-precision laser dust sensor, which can accurately see the micro-world. The minimum resolution is 0.3 μm. The concentration of PM2.5 and PM10 particles is clear at a glance. 500ms/time detection speed, rapid upload data, fast and endless. Without using external sampling hardware, the current formaldehyde concentration in the air can be output digitally in real time by using the principle of gas diffusion, which is convenient and fast to use. It has high sensitivity, high stability, strong anti-interference ability and long life. The factory has been calibrated by standard gas. Users do not need to process complex signal of sensors, nor do they need professional equipment to calibrate. Batch consistency (+0.01 mg/m³)。 Support UART, PWM, DAC and other output modes. Different modules can be customized according to the needs of different manufacturers.
