The host can query the LM75 through its IC interface to read temperature at any time. The LM75 temperature sensor includes a delta-sigma analog-to-digital converter, and a digital overtemperature detector. But in this case you need cold junction compensation. ESP32 and LM75 temperature sensor example. Depending on your range you nedd to do some linearizing of the R/T characteristic and/or use lookup tables.ДЄnother solution is a thermocouple based one. If you need even higher temperature measurement, one of the circuits suitable for high precision temperature measurement is a Wheatstone bridge with an NTC thermistor used as one bridge leg. The open-drain Overtemperature Shut-down (O.S.) output becomes active when the temperature exceeds a programmable limit. The host can query the LM75 at any time to read temperature. Overall MCP9808 is clearly better than LM75, and, off course, more expensive. The LM75 is a temperature sensor, Delta-Sigma analog-to-digital converter (9-bit digital temperature readings) and digital over-temperature detector with I2C interface. They are many factors than can influence badly reading process, from power supply to decoupling and PCB design. If you stay under 100вЊ, you can have, in terms of accuracy: LM185 is not an adjustable band-gap voltage reference diode? The output of this sensor is sometimes noisy tough, specifically at higher temperatures. IвЂ™ve been using LM185, not satisfied though. As long as slave device addresses are unique, everything will work just fine: OLED display, LM75 temperature sensor, MPU6050 gyroscope. You can find the source code and the project. This example assumes that an mbed application shield is used and that the SDA and the SCL lines are connected to Arduino define pins.

Data is collected from the thermometer and sent by UART.

Yes, the I2C bus allows connecting multiple slave devices to single pair of SCL SDA wires. The TWI Sensor Example demonstrates how to use the I2C interface by communicating with the thermometer (LM75). However, since youвЂ™ve already used both, could you please let us know about the accuracy of these sensors? I was wondering if they can be accurate up to 0.1K. One of the advantages of the ESP32 microcontrollers over the competitions is dual-core architecture and two I2C buses. This interface is really low speed and minimalist, its based on specific optos.

Example minimal serial port I2C interface. add more I2C components, add your own driver if you send it to me.
