Here I will keep a few "recipes" for devices I've flashed with ESPurna, using various sensors.
NodeMCU with HTU21D temperature sensorΒΆ
NodeMCU board, using HTD21D
(datasheet)
temperature and humidity sensor, clone of the SI70xx
(datasheet).
This is an I2C sensor, which just needs SCK, SDA, +3.3V and GND.
