MPM10 SERIES LASER PARTICLE SENSOR Product Introduction The MPM10 series sensor module uses the principle of optical scattering to detect the concentration of dust in the air. It can collect and calculate the number of suspended particles of different sizes in the air per unit volume, that is, the particle concentration distribution, and then convert it to mass concentration. The particle concentration value is output in the form of a universal UART digital serial port, or it can be output through the IIC serial port and PWM level signal number. The unit of counting data is pcs/0.1L, and the unit...

MPM10 SERIES LASER PARTICLE SENSOR Pay attention to the Circuit design: 1. MPM10 series working voltage is 5V. The data communication and control pins are both 3.3V as the high level, so the motherboard MCU connected to the communication should be with 3.3V power supply. If the motherboard MCU is powered by 5V, need to add a level conversion chip or circuit on communication lines (RXD, TXD) and control lines (SET, RESET). 2. There is pull-up resistors in SET and RESET , if no need,please suspend it. 3. During the application of sleep function: the fan stops working in sleep status, and it takes...
