Frequently Asked Questions

What is the communication protocol for the UMW TMP101NA sensor?

The TMP101NA uses a standard I2C (Inter-Integrated Circuit) two-wire serial interface for communication. This allows it to connect directly to the I2C pins on microcontrollers like Arduino, ESP32, or Raspberry Pi using just the SDA (data) and SCL (clock) lines, along with power and ground.

What is the operating voltage range of the TMP101NA?

The sensor operates from a supply voltage (VCC) of 2.7 volts to 5.5 volts. This wide range ensures direct compatibility with both 3.3V and 5V logic systems commonly found in development boards and embedded systems without requiring a voltage level shifter.

What is the temperature measurement range and accuracy?

The TMP101NA can measure temperatures from -55 degrees Celsius to +125 degrees Celsius. For specific accuracy figures (typically within ±1°C or ±2°C over certain ranges), please consult the official UMW datasheet, as accuracy can vary with supply voltage and measurement resolution settings.

How do I mount and solder this sensor?

The TMP101NA comes in a surface-mount device (SMD) SOT-23-6 package. It is designed for reflow soldering onto a printed circuit board (PCB). Proper soldering techniques and a soldering iron with a fine tip or a reflow oven are required for reliable installation.
