is a project for monitoring the weight of a beehive including climate sensors for temperature,humidity and barometric pressure we can optional add up to 3 external temperature sensors, so we can monitor the temperature in the beehive
keep in mind, that the max. airtime/node in lora is limited to 30 sec. per day with sf=7 .... abaout 500 messages with sf=12 ... max 20 messages per day ! ... we send the data with an intervall of 5 minutes -> 288 messages per day
- heltec cubecell AB01
- Waveshare BME280 (Environmental Sensor, Temperature, Humidity, Barometric Pressure Detection Module Low Power Consumption I2C/SPI Interface)
- optional: DS18B20 temperature sensor (1-Wire for external use)
- 3,7V 1100mAh Lipo Accu 1S 3C
- optional: solar panel 1W 5V 100mA
- this version is tested with the Dragino LG02 LoRa gateway without TTN-Support. If you need TTN support, choose https://github.com/thomasX/monitoredLoraBees

we use the thingspeak network with the following field-definition it is possible to use the Android and IOS-APP from the honeyPi project (http://www.honey-pi.de ). so we have no extra app to produce
| Field | Usage |
|---|---|
| field1 | temperature inside the hive |
| field2 | temperature outside the hive |
| field3 | humidity |
| field4 | air pressure |
| field5 | air quality |
| field6 | weight |
| field7 | unused |
