You have to design a temperature sensor. Chat with me to know more details. Will give details. The main thing is it should be of small size.

Details

You are free to use existing boards, such as esp2286 etc

Size of complete sensor including battery and sensor: 50mm x 50mm x 30mm

Power Backup: 5 days, reporting frequency: 6min

Technology: Wifi

Must be uploadable on any open source IOT platform

The board should have a charger for the battery.

If not using the chargeable battery, then the battery backup should be 1 month.

We are open for board-Integrated temp sensor

We shall prefer if you can combine humidity sensor as well.
