Nice to read that there are already all kind of LoRa beehive monitors! I recently made one myself (for my sister, she has two beehives) as a learning project (my first pcb design and first LoRa project). Made a simple beacon with the RFM95 and an attiny85v on a coin cell:
Both the attiny85 and the RFM95 already have an internal temperature sensor (both with a resolution of 1 degree C). With some calibration and sub degree interpolation (by averaging multiple reads) a nice accuracy seems possible:
red = external DHT22 temperature sensor
purple = averaged temperature measurements from the beacon
Also designed a small 3D printed enclosure in an appropriate shape :
I expect the module to have a lifetime of around 3 years on a single CR2032 coin cell, measuring the temperature every hour and sending 4 hours of data at once 6 times a day (+ a 7th message with the coin cell voltage and some backup temperature data in case one of the messages isn’t received).
Was a fun project to work on

and your enclosure is in ‘beehive’ style… very nice project !

Hello everyone,
Since 6 months I develop a hive connected. I use an ESP32 with weight sensor, temperature etc through a Blynk application Wifi. But the wifi is not everywhere so I went here to see how I could do to use the Lora system. I present to you what I have already achieved.

Hi,
yes LoRaWAN is a good choice if you need long range and battery operated sensors.
start with some info on this network here
also check if there is a gateway in range of your Hives, if not you need to buy/build one
- I was searching the BLYNK site… he

Irish innovative startup that raised 1.5M in funding are (… cough!!!) busy little bees in this space.

and still keeping it shrinking (more thin). Now being migrated to nRF52832 (on picture still nRF51822) and getting rid of extra height. Easily programmable with mbed. This is just bluetooth temperature beacon for in-hive placement. Bigger sensor takes measurement long-distance

Hi Christophe,
Very cool setup, I was working with a smart beehive group here about 5 years ago. They since moved off and decided to close source everything and I continued on my other stuff. Anyways, I have a question about your load sensor. How does it work with a continuous load? In my limited research (back then) I noted they are good to weigh things but not necessarily have the weight loading it all the time due to drift.
Looks like your using a feather, there is a LoRa version of the feather (Adafruit Feather 32u4 RFM95 LoRa Radio) or you can use the pycom which has the ESP32 and a lora on the same board.
Thank you very much Olesik, regarding the weight measurement, yes there is drift, especially when it is cold. I have not yet controlled the cold temperature drift but I will adjust the value in concordance. I will look to the Adfruit Feather but I think that board is not using Arduino ID to program?
