Fingerprint Sensor AS608 - A Beginner's Guide
One touch can replace keys. This project uses an optical fingerprint sensor to enroll users and then grant access with a quick scan.
read tutorial →The MAX31865 RTD Platinum Resistance Temperature Sensor is a temperature sensor with analog and digital output designed for temperature logging, thermal control, and equipment monitoring. It is a practical fit for makers, students, and engineers who want reliable sensor data in embedded builds.
Key details include Interface: Analog and digital.
| Product | Sensor style | Standout |
|---|---|---|
| MAX31865 RTD Platinum Resistance Temperature Sensor | temperature sensor with analog and digital output | Current item |
| Adafruit PT100 RTD Temperature Sensor Amplifier - MAX31865 | temperature sensor with SPI | temperature sensing, breakout-board format |
| Temperature Linear LM35 Analog Sensor | temperature sensor with analog output | analog output, temperature sensing |
| Temperature Sensor Waterproof DS18B20 kit | temperature sensor with 1-Wire | waterproof build, temperature sensing |
This sensor is a good fit for thermostats, incubators, battery monitors, weather nodes, and thermal data loggers.
Pair it with an Arduino-compatible board, ESP32, or Raspberry Pi, plus a breadboard and jumper wires for quick setup and testing.
Useful add-ons include probe mounts, thermal paste if needed, and a data logger, depending on how you plan to power, mount, and log the sensor.

Many modules in this style expose both analog and digital pins. Use the analog pin for raw readings and the digital pin for threshold-based switching, if available. Sensor response time depends on airflow, mounting, and thermal contact. Keep heat sources and self-heating from nearby parts in mind.
