High Humidity Sensors

A project log for Bee hive health monitor

This project will monitor the weight changes in the hive along with some environmental items to provide real time indicators of hive health

I do not want to double post so the link below will point you to the relevant text for this topic. The TL;DR is that the DHT21 type sensors will not reliably work outside in any place that regularly sees relative humidity above 60%. That makes it a poor choice for the inside of a warm bee hive.

The SHT21 from Sensirion and the HDC1080 from TI seem to be good value sensors that have successfully passed our testing at humidities in the 95-99% range.
