Good sensor, easy integration

Used this for a smart car project to monitor motor temperature. It was very easy to wire up. The only reason for 4 stars is that the pins were slightly bent upon arrival, but easily fixed.

Standard LM35 performance

Exactly what you expect from an LM35. No surprises, just solid performance. The breakout board makes it much easier to use than the raw component.

Great for kids' projects

My son used this for his science fair project on room temperature monitoring. It was safe to handle and worked exactly as described in the tutorials we found online.

5 FAQ

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

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

Q: Do I need any external resistors to use this module?

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

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

A: Yes, this module operates perfectly with 5V logic levels found on standard Arduino boards like the Uno and Nano.

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 high accuracy.

Q: Is the output voltage linear with temperature?

A: Yes, the output voltage increases linearly by 10mV for every 1°C rise in temperature, making calculations very straightforward.
