Perfect for my Arduino robot car

This LM35 module works flawlessly with my smart car project. The readings are stable and the calibration was spot on right out of the box. Very easy to integrate.

Good value, accurate enough

For the price, this is a solid sensor. It's not laboratory grade, but for hobbyist electronics and temperature monitoring in a car, it performs very well.

Solid component

The build quality of the PCB is decent. The pins are sturdy. Only minor issue is the wire length could be slightly longer for some chassis setups.

5 FAQ

Q: Do I need an external resistor to use this sensor?

A: No, this breakout module includes all necessary components. You only need to connect VCC, GND, and the Signal pin to your microcontroller.

Q: What is the maximum temperature this sensor can measure accurately?

A: The LM35D variant included in this module is rated for temperatures up to 100°C (212°F) with good linearity.

Q: Does this module work directly with 5V Arduino boards?

A: Yes, the LM35 module operates comfortably within the 4V to 30V range, making it fully compatible with 5V Arduino boards like the Uno and Mega.

Q: Can this be used outdoors in a weatherproof enclosure?

A: The sensor itself is durable, but the PCB module is not waterproof. You must house it in a weatherproof enclosure if using it outdoors.

Q: Is the output linear across the entire range?

A: Yes, the LM35 provides a linear output voltage proportional to the Celsius temperature, scaling at 10mV per degree Celsius.
