There is one thing I always found fascinating : weather. Especially the temperature and humidity. So one of my first TheThingsNetwork projects I made was a DHT22 based beacon who allowed me to measure every 15 minutes the temperature and the humidity. After the measurement was done the beacon would…

There is a update to report to the ENV system. Changes : support for alarm and warning levels with mailer (email) and telegram bot support. own map marker generator [ttn_env_map] [ttn_env_chart] Updated sourcecode at : https://github.com/ph2lb/LoRaWAN_TTN_Env

I use runmode=0 with the BME280 That forces it to sleep immediate. Then I do a reading through a force read ( SparkFunBME280.h ) void bmeSetup() { bme.settings.commInterface = I2C_MODE; bme.settings.I2CAddress = 0x76; bme.settings.runMode = 0; } void rTEMP() { bmeForceRead(); temp …

During my Monday shopping routine I found a birdfeederhouse at the Lidl. The price was right so could resist to by it for a side project. [Lora_env_birdfeeder_001]! Step 1 : remove the roof to get access to the internals of the house (and cut a PVC pipe) [Lora_env_birdfeeder_002]! Step 2 : Remo…

First results are coming in : Below the result of the reference node. [ph2lb-001] Then the result of the birdfeeder node. It seems to work but there is a big difference between them in the humidity. :open_mouth: Maybe there isn’t enough air flowing throw the birdfeeder (needs a extra chimney) or…

[image] lex_ph2lb: a big difference between them in the humidity indoors and outdoors :wink:

are you happy with that BME280 sensor ? and what happends to the components and PCB’s in the open air after a while, did you protect the board with an (anti condens) spray or something ?

Yep quite happy with the BME280. THe components holding out nice, but I’m going apply a layer of clear varnish on one of them for a test. For but for now all seems good.

Hi, the BME280 is connected to A4 and A5 on the Arduino pro mini and did you remove the power LED from the Arduino? I want to use your setup for an indoor monitor to detect water damage from the level above the holiday home. Last time there was a undetected water damage above so the water runs in t…

Hello Stefan, sorry to hear about your holiday home damage, that really sucks. Indeed I removed the power LED but also the Power regulator from the Arduino. That drops the deepsleep current bigtime. Using the BME280 as a higher humidity indicator should work when you have base line. Iḿ thinking…
