eCO2, humidity & temperature sensor |

29/10/2020· It uses an esp8266, a SGP30 eCO2 sensor and a DHT11 for humidity & temperature. A high CO2 concentration means you should ventilate the room (and so, indirectly can help to limit COVID-19 indoors). SPG30 doesn’t detect CO2 but can make a « equivalent CO2 » (not great but sensor is cheap, about 10 €). It displays value on an OLED screen ...

Interface PIR Sensor With NodeMCU : 6 Steps (with Pictures) - …

Connecting PIR sensors to a NodeMCU is really simple. The PIR acts as a digital output so all you need to do is operate the pin to flip high (detected) or low (not detected). Check out the images for more details. Most PIR modules have a 3-pin connection at the side or bottom. The pinout may vary between modules so check the pinout carefully! Power is usually 3-5v DC input. The circuit connections are …
