Great for learning
As a student learning about embedded systems, this module was perfect. Clear documentation online and the analog output is easy to read with an ADC. No issues so far.

Excellent consistency
Bought three of these for a multi-zone heating project. All three sensors provided consistent readings relative to each other, which saved me a lot of calibration time.

Good accuracy, easy to use
I used this for a home automation temperature monitor. Setup was straightforward. Only giving 4 stars because the included header pins were slightly bent, but easily fixed.

Works well for plant monitoring
Using this to monitor soil temperature in my greenhouse. It handles the humidity well inside its casing. Would prefer a longer cable, but I can extend it myself.

Reliable and Compact
Small form factor makes it easy to fit into tight enclosures. The response time is quick when testing rapid temperature changes. Highly recommended for DIY electronics.

Perfect for Arduino Projects
This thermistor module works flawlessly with my Arduino Uno. The readings are stable and match my calibrated thermometer very closely. Great value for the price.
Q: What library should I use for ESP32?
A: You generally do not need a specific library. You can simply read the analog pin using the standard analogRead() function in the ESP32 Arduino core and apply the Steinhart-Hart equation or a simple beta parameter formula to convert resistance to temperature.
Q: Can this measure temperatures above 100°C?
A: Yes, the operating range extends up to +125°C. However, please ensure your wiring and surrounding components can also withstand these higher temperatures.
Q: Does this come with a waterproof casing?
A: No, this specific module is not waterproof. The PCB and components are exposed. For wet environments, we recommend applying conformal coating or housing the module in a sealed enclosure.
Q: Is this compatible with Raspberry Pi?
A: Yes, it is compatible. Since the Raspberry Pi GPIOs do not have built-in analog inputs, you will need to connect this module via an external ADC (like the MCP3008) to read the temperature data.
Q: What is the length of the sensing probe?
A: The thermistor bead itself is encapsulated in a small epoxy tip approximately 5mm in length. The PCB board dimensions are 20mm x 15mm as listed in the specifications.
