Introductie
The ESP module can read a BMP085 temperature/Barometric pressure sensor using the I2C protocol.
The DHT sensor needs to be connected to a the I2C pins on the ESP module. These pins can be configured on the hardware tab.
Hardware
The BMP085 sensor can be connected directly to an ESP module by using the two pins SDA and SCL.
Use 3.3V break boards only. Sometimes, it could be necessary to add a 100nF ceramic capacitor across the power terminals of the BMP085/180
Software
Custom Sketch
ESP Easy
Use the device tab on the ESP Easy webinterface and create a new task by editing one of the available tasks. Select "BMP085 Barometric Sensor" from the dropdown box and enter the IDX found in the Domoticz device page. That should be all.
