# SensorTransmitter

Sensor Data FSK Transmitter based on RadioLib using SX1276 or CC1101 

This project is closely related to [BresserWeatherSensorReceiver](https://github.com/matthias-bs/BresserWeatherSensorReceiver)

## Use Cases

* Emulation of sensors for testing purposes

* Emulation of sensors while replacing the data with entirely different sensor values,

  e.g. using the manufacturer's temperature sensor protocol to display snow depth instead.

* Repeater (combined with receiver)

## Supported Protocols

- [x] Bresser 5-in-1

- [x] Bresser 6-in-1

- [x] Bresser 7-in-1

- [x] Bresser Lightning

- [ ] Bresser Leakage

## Sensor Data Provisioning Options

See sensor types in [WeatherSensor.h](https://github.com/matthias-bs/BresserWeatherSensorReceiver/blob/main/src/WeatherSensor.h)

Select option in [SensorTransmitter.h](SensorTransmitter.h).

### Raw Data

   ```

   uint8_t payload[] = {0xEA, 0xEC, 0x7F, 0xEB, 0x5F, 0xEE, 0xEF, 0xFA, 0xFE, 0x76, 0xBB, 0xFA, 0xFF,

                         0x15, 0x13, 0x80, 0x14, 0xA0, 0x11, 0x10, 0x05, 0x01, 0x89, 0x44, 0x05, 0x00};

   ```

### [class WeatherSensor](https://github.com/matthias-bs/BresserWeatherSensorReceiver/blob/main/src/WeatherSensor.h)
