Reliable sensor
Bought multiple units for a classroom setup. All of them performed consistently. No dead on arrival units.

Works as expected
Standard LM35 performance. Make sure to use a capacitor if you experience noise in the analog reading.

Good value for money
Solid build quality. It takes a moment to stabilize when powered on, but accuracy is decent for hobby projects.
Q: Do I need a library to use this with Arduino?
A: No library is required. You can read the analog pin and convert the voltage to temperature using a simple formula.
Q: What is the maximum cable length for the output?
A: We recommend keeping connections short to avoid noise interference. Use shielded cables for longer distances.
Q: Is this sensor waterproof?
A: No, the module is not waterproof. Please use an enclosure if using it in humid or outdoor environments.
Q: Can this sensor operate on 3.3V logic?
A: Yes, the LM35 can operate down to 4V, but the output is compatible with 3.3V microcontrollers if powered appropriately.
Q: Does it measure negative temperatures?
A: The LM35DZ model typically measures from 0°C to 100°C. For negative temperatures, ensure you have the full range variant.
