Sensor Description

WH52

Additional information

WH52 miniature temperature ang humidity sensor from Relsib. Can also transmit batt level and rssi. temperature: -20 …+55 ±0,4 °С, humidity: 5...97 ±3 % battery: CR1632 Bluetooth 4.0 (Bluetooth Low Energy) dimensions: diametr 33 mm., higst 8 mm. Work with Android app "Termosha". With app can setup min/max alarm levels to red/green LED blinking on sensor and sound alarm on app. Some kind of Sensirion sensor is used, which applies the temperature formula: ((2-byte-data/65535)/175-45).

I modified 2 files to receive and calculate temp data: \custom_components\ble_monitor\const.py \custom_components\ble_monitor\ble_parser\relsib.py Files attached in format txt.

But i can`t find and receive humidity & batt data.

There seem to be three packages. My educated guess is that the second is humidy

05 16 0918 4dea --> temperature --> 4dea (hex) = 19946 (dec) --> ((19946/65535)175-45) = 8.26 degree 05 16 1a18 b14c --> humidity??? --> b14c (hex) = 45388 (dec) --> ((45388/65535)175-45) = 76.2 % RH 07 16 a2aa 30333531 --> not sure
