Introduction
|
|
------------
|
|
|
|
|
|
Specifications:
|
|
* Temperature (-40C to +85C)
|
|
* Barometric pressure (300-1100 hPa)

Wiring
|
|
------
|
|
|
|
.. code-block:: none
|
|
|
|
ESP BMP085
|
|
GPIO (4) <--> DA (SDA)
|
|
GPIO (5) <--> CL (SCL)
|
|
|
|
Power
|
|
3.3V <--> + (plus)
|
|
GND <--> - (minus)
|
|
|
|
.. note:: If you have change the I2C settings in the hardware setup you need to connect to those instead of GPIO 4 and 5.
|
|
|
|
.. note:: Only use 3.3V BMP085/180 boards. The ESP pins are not 5V tolerant. Depending on the make of the BMP085/180 board,
|
|
pull-up resistors on SDA and SDC may be absent. 4k7 types are fine. When more I2C devices are being used, only one set
|
|
of pull-up resistors is required or even allowed. It may be necessary to add a ceramic 100nF capacitor across the power
|
|
lines, close to the BMP085/180 board.

Task settings
|
|
~~~~~~~~~~~~~
|
|
|
|
* **Device**: Name of plugin
|
|
* **Name**: Name of the task (example name **BMP**)
|
|
* **Enable**: Should the task be enabled or not
|
|
|
|
Sensor
|
|
^^^^^^
|
|
|
|
* **Altitude**: Set the level above sea for your unit. This is done in order to get a correct pressure value.
|
|
|
|
.. include:: DataAcquisition.repl
|
|
|
|
* **Interval**: How often should the task publish its value (5..15 seconds is normal).
