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 Humidity Digital Sensor SHT30-D is a humidity sensor with i2c designed for temperature logging, thermal control, weather nodes, 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: I2C.
| Product | Sensor style | Standout |
|---|---|---|
| Humidity Digital Sensor SHT30-D | humidity sensor with I2C | Current item |
| Temperature & Humidity Sensor SHT20 I2C Waterproof Probe | temperature and humidity sensor with I2C | waterproof build, I2C interface |
| DHT22 Temperature and Humidity Digital Sensor | temperature and humidity sensor with digital output | digital output, humidity sensing |
| Temperature Humidity Sensor HDC1080 | temperature and humidity sensor with I2C | digital output, humidity sensing |
This sensor is a good fit for thermostats, incubators, weather stations, battery packs, 3D printer enclosures, and cold-chain logging.
Pair it with an Arduino-compatible board, ESP32, or Raspberry Pi, plus an I2C cable or 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.
