Sensors for weather stations, incubators, greenhouses and room monitors: DHT11 and DHT22, DS18B20 1-Wire sensors and stainless waterproof probes, BME280 and BMP280 combos with pressure, BME680 with gas, SHT30 waterproof probes, AHT10 and AHT20, NTC thermistors, the MAX30205 body temperature sensor and flame sensor modules.
Choosing a temperature sensor
The DHT11 is cheap but coarse. The DHT22, AHT20 and SHT30 measure humidity more accurately. For liquids, soil or anything outdoors, the waterproof DS18B20 probe is the usual choice, and several can share one pin. The BME280 adds air pressure on I2C. NTC thermistors need an analog input and a resistor, but cope with higher temperatures.
