Looking for a HW and SW Engineer, which could develop a UV Meter based on ASM Osram AS7331 Chip.
Data from Sensor Head to MCU is done via I2C Interface. Sensor should be not part the MCU PCB, as there will be two Versions of Meter (integrated and extended via cable).

MCU should be ESP32 or STM32. 

Based on the data provided, MCU should calculate UVC, UVB, UVC and UV Index. For UV Index, only a certain part of the supplied data of the UVB Sensor is used (see info of Datasheet of AMS Osram).

Measurement should be talken by pressing a buttom and/or using a Mobile App to start the measurement.

Results should be placed in a LCD Display all at the same time showing value and units and/or displayed in the Mobile App.

Firmware should be able to be updated via Wifi/BLE.

A posibility to calibrate the UNit/Sensor must be available, but not accessable for EndUser.

For future extension (datalogger just via App) a MicroSD Slot should integrated to save data, tu upload into the App or even to a PC (csv or excel File compatible).

Pls provde an estimate and timeframe
