esp_log.h to log the informational messages, and driver/temp_sensor.h for the functionality of the in-built temperature sensor. However, this library will only work if the configured target is either ESP32S2 or ESP32C3.
In this article, I will show you how to use the LM35 temperature sensor with the ESP32 microcontroller. The LM35 series are precise temperature sensors that give you a voltage output directly proportional to the Centigrade temperature that it senses. Monitoring temperature is critical in many diffe...

and BLE Beacon with two 32-bit high-performance LX6 CPUs. The frequency adjustment range of this module ranges from 80MHz to 240MHz. It adopts a stage pipeline architecture, a Hall sensor, an on-chip sensor, atemperature sensor, etc. This type of module is appropriate for industrial wirele...
Initialize the BME68X sensor according to the configured communication method (I2C here). If there are any errors or warnings during initialization, corresponding messages will be output to the serial port Set the sensor's temperature, pressure, and humidity measurement configurations, and set the ...
