Product: Seeed Studio Grove ?? Air Quality Sensor(BME688) with built-in AI, High-Performance 4-in-1, Gas,Humidity, Pressure and Temperature sensor High Accuracy Thermistor: NCP18WF104F03RC (NTC) Grove compatible interface Easy to use
Range of measurement:0.3~1.0; 1.0~2.5; 2.5~10 Micrometer (um) Single Response Time:< 1 Second (s) DC Power Supply:Typ:5.0 Min:4.5 Max: 5.5 V Working Temperature Range:-10~+60 C
Measuring output: PM2.5,PM10 Range: 0.0-999.9 ug/m3 Power supply voltage: 5V Maximum working current: 100mA Particle diameter resolution: Less than 0.3um
Dual signal output (analog output and TTL level output) The TTL output effective signal is low. Analog output 0 ~ 5V voltage, the higher the concentration the higher the voltage. Good sensitivity to hydrogen sulfide, liquefied gas, natural gas, city gas, and smoke. with long service life and reliable stability fast response recovery characteristics
