Advantage of this sensor is fast and easy installing by the non qualified personal. The sensor is designed for large agriculture facility with many greenhouses where is needed to be controlled temperature and humidity, the atmospheric pressure is for control the motor of air inlet and outlet. With help of the sensor installed outside the greenhouse provide information about positive/negative pressure inside the greenhouse. Finlay the software read accurate temp/humid value of the Si7021, and only atmospheric pressure of BMP180, the temperature sensor inside the BMP180 is used only by the sensor itself to provide accurate atmospheric pressure measurements. The sensor can be used also for home automation, and drone applications where is needed correction of the UAV barometric sensor compared to the ground barometric sensor, also humidity measurement can help the pilot to calculate more accurate flying time.

This project is impressive, I really like it. Pity it is so silent about it. After all this work, are you not willing to finish it?

@gohan said in Arduino Pro Mini Shield for RFM69(H)W: If I remeber right that pin is used as input so the RFM69 is not receiving any 5v signal. In addition there are people claming they have the RFM69 module working on 5v on data pins and 3.3v on vcc, but I hardly suggest to do it. thank you just what i thought . about direct 5v on data...well... i seen a big red sign saying n :DONT do it! lol Level converters are so cheap...that i ordered 5 or 10 thoguether with rfm69 board. sorry about hijack this topic, i though i was on general discussion

Sorry for not noticing your post earlier @skywatch The example was originally designed for BMP085. When the BMP180 became widely available, the buy link was updated to the newer version with the note "replaces the old BMP085". Both use the same library. At a later stage, a MySensors user suggested changes to the example sketch to use the BME sensor instead. I don't know why this change was made, but my guess is that the user liked the BME sensor better. I don't know why the change was accepted without updating the build page, but my guess is that since the commit doesn't mention the change of sensor and the amount of code changed is quite large (369 additions and 252 deletions) nobody noticed that a new sensor was used. I'm trying to address the sensor change in https://forum.mysensors.org/topic/9801/bmp-e-atmospheric-pressure

Hi, possible to share pcb files? THX MiKa

Still this code is working?

Could you perhaps try to introduce a few delays and see if that fixes the problem? Would be good if the sketch works without debug enabled.
