This compact breakout combines the STCC4 CO2 sensor with a Sensirion SHT41 temperature and humidity sensor for convenient indoor air monitoring. The STCC4 measures true CO2 using a thermal conductivity method rather than estimating from VOCs, and the onboard SHT41 helps improve the CO2 measuremen...

SKU: LB-LR-DIGI-TEMP-1M-UA

The Little Bird 1-Wire Digital Temperature Sensor for Raspberry Pi — a plug-and-play solution for environment sensing, data logging, and IoT applications. Simply plug it onto the Raspberry Pi GPIO header — no breadboard, jumper wires, or additional components needed. This is the unassembled vers...

SKU: DF-DFR0198

This is a waterproofed version of the DS18B20 Temperature sensor. Handy for when you need to measure something far away, or in wet conditions. While the sensor is good up to 125°C the cable is jacketed in PVC so we suggest keeping it under 100°C. Because they are digital, you don't get ...

SKU: PR-PIM357

The state-of-the-art BME680 breakout lets you measure temperature, pressure, humidity, and indoor air quality, and is Raspberry Pi and Arduino-compatible! Use this breakout to monitor every aspect of your indoor environment. Its gas resistance readings will react to changes in volatile organic...

SKU: AF-4867

The Adafruit SCD-30 is a true NDIR (Non-Dispersive Infrared) CO2 sensor that directly measures carbon dioxide concentration in ambient air, rather than estimating it from volatile organic compounds. With an integrated SHT31 temperature and humidity sensor, it provides comprehensive environmental ...

SKU: DF-DFR0067

This Gravity-compatible DHT11 sensor provides calibrated digital temperature and humidity readings via a single data pin. With an integrated 8-bit microcontroller and factory-calibrated coefficients stored in OTP memory, it delivers reliable measurements with minimal setup. The Gravity 3-pin int...

SKU: AF-2857

The Adafruit Sensirion SHT31-D is a high-accuracy temperature and humidity sensor with a true I2C interface and PTFE filter for protection against dust and contaminants. Part of Sensirion's third-generation SHT sensor family, it delivers ±2% relative humidity and ±0.3 °C temperature accuracy for ...

SKU: DF-SEN0198

What sensor should you use when you need to measure temperature? Most people will think of a DS18B20 temperature sensor first, but this sensor is only capable of measuring temperatures up to 125C. In order to measure temperatures greater than 100C you will need something with a greater temp...

SKU: AF-1899

The Adafruit HTU21D-F is an accurate I²C digital temperature and humidity sensor breakout board. With typical humidity accuracy of ±2% (optimised for 5–95% RH) and temperature accuracy of ±1°C across -30 to 90°C, it's a reliable and affordable choice for environmental monitoring projects. This b...

SKU: AF-576

Put a temperature meter anywhere with this very handy display. This panel meter displays the temperature of the attached waterproof 1% thermistor in °C. It does require a DC voltage to run, at 4.5-30VDC. It has reverse polarity protection in case you swap the power leads by accident. To use, sim...

SKU: AF-3328

The Adafruit PT100 RTD Temperature Sensor Amplifier is a breakout board for the MAX31865 precision RTD-to-digital converter.
