Fixed phosphine detector

The YF8500 series detector is a gas diffusion type. The detection principle is that when the target gas enters the gas probe section, the internal sensor will immediately emit an induction. Sensors generate certain electrical signals based on the concentration of gas. After being amplified by the circuit, the signal is processed by the CPU through AD sampling, temperature compensation, and intelligent calculation to output accurate 4-20mA current signals, RS485 communication signals, 0-5V voltage signals, ZIGBEE, NRF, WIFI, GPRS wireless signals, etc.
