I am looking to build a temperature and humidity sensor (preferable temperature range 0-100C), which can be powered by a piezo energy harvester (mechanical vibrations).
The two sensors should occupy as little space as possible and should be able to connect to a BLE module.
I would like to know if you can assist me in finding these 3 components (temperature sensors, energy harvester and BLE module) and to understand which additional pieces I would need to put everything together.
