The SHT30-D sensor has an excellent ±2% relative humidity and ±0.5°C accuracy for most uses. Unlike earlier SHT sensors, this sensor has a true I2C interface. The enclosed box is a Sensiron SHT-30 digital sensor (much like our breakout here or this weather-proof mesh sensor) but with the 4 data/power wires brought out to bare wires. Any SHT-3x code...

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, simply connect the thin red wire to a positive supply, and the thin...

Polyimide Tape (sometimes referred to by the brand name Kapton Tape) is an interesting addition to your toolbox! Polyimide Tape remains stable across a wide range of temperatures from about −269°C to +400°C. Along with aircraft, spacecraft, and x-rays, polyimide tape is also used in electronic manufacturing and 3D printing. Due to its large range of...

The AHT20 is a nice but inexpensive temperature and humidity sensor from the same folks that brought us the DHT22. You can take sensor readings as often as you like, and it uses standard I2C so its super easy to use with any Arduino or Linux/Raspberry Pi board. This sensor has a typical accuracy of +- 2% relative humidity, and +-0.3 °C at 20-80% RH and 20-60...

The long-awaited BME688 from Bosch gives you all the environmental sensing you want in one small package. This little sensor contains temperature, humidity, barometric pressure, and VOC gas sensing capabilities. All over SPI or I2C at a great price! The BME688 is a 'drop in' replacement for the BME680 - it adds a method of programming the gas-sensor heater for...

The long awaited BME680 from Bosch gives you all the environmental sensing you want in one small package. This little sensor contains temperature, humidity, barometric pressure, and VOC gas sensing capabilities. All over SPI or I2C at a great price! Like the BME280 & BMP280, this precision sensor from Bosch can measure humidity with ±3% accuracy,...

These 1-wire digital temperature sensors are fairly precise (±0.5°C over much of the range) and can give up to 12 bits of precision from the onboard digital-to-analog converter. They work great with any microcontroller using a single digital pin, and you can even connect multiple ones to the same pin, each one has a unique 64-bit ID burned in at the...

Wide range, low power temperature sensor outputs an analog voltage that is proportional to the ambient temperature. To use, connect pin 1 (left) to power (between 2.7 and 5.5V), pin 3 (right) to ground, and pin 2 to analog in on your microcontroller. The voltage out is 0V at -50°C and 1.75V at 125°C. You can easily calculate the temperature from the voltage...

The Adafruit PCT2075 Temperature Sensor is a 'code compatible' drop-in replacement for a very common I2C temperature sensor, the LM75. Compared to the LM75, however, the 11-bit ADC in the PCT2075 provides more precise measurements when compared to the LM75's 9-bit ADC. Additionally, because the PCT2075 allows the address pins to work in three states (high, low,...

The HTU31-D is the third generation of temperature-humidity sensors from TE - and a great follow-up to the popular HTU21-D sensor. Like the HTU21, the '31 is great for sensing temperature and humidity, with excellent specifications. This I2C digital humidity sensor is an accurate and intelligent alternative to the common DHT-series sensors, at about the same price!...
