!> This feature is not included in precompiled binaries.
To use it you must compile your build. Add the following to user_config_override.h:
#ifndef USE_MLX90614
#define USE_MLX90614 // [I2cDriver32] Enable MLX90614 ir temp sensor (I2C address 0x5a) (+0.6k code)
#endif
The MLX90614 is an infrared thermometer for non-contact temperature measurements.
| MLX90614 | ESP8266 |
|---|---|
| GND | GND |
| VCC | 3.3V |
| SDA | GPIOx |
| SCL | GPIOy |
In the Configuration -> Configure Module page assign:
- GPIOx to
I2C SDA (6) - GPIOy to
I2C SCL (5)
After a reboot the driver will detect MLX90614 automatically and display Temperature measurements.
Sensor sends a tele/%topic%/SENSOR JSON reponse:
tele/tasmota/SENSOR = {"Time":"2019-11-11T00:03:30","MLX90614":{"OBJTMP":23.8,"AMBTMP":22.7}}
This driver will also work with MLX90615 sensor with some code alterations.
