The sensor(chip) used in the module is designed with Sensirion’s CMOSens® technology. The chip is well calibrated, linearized and compensated for digital output. The typical accuracy of this module can be ±2%RH (for relative humidity) and ±0.3°C (for temperature). This module is compatible with ...

The resistance of a thermistor will increase when the ambient temperature decreases. It’s this characteristic that we use to calculate the ambient temperature. The detectable range of this sensor is -40 - 125ºC, and the accuracy is ±1.5ºC

Grove-Temperature & Humidity Sensor Pro is a high accuracy temperature and humidity sensor based on the DHT22 module (also known as AM2302 or RHT03). High-cost performance and high precision make it ideal for temperature and humidity monitoring of Arduino and Raspberry Pi, you can also use it...

Gardens are a way to contribute to contrast the global warming. Maybe you don't have a backyard, but you have a balcony or a windowsill, in which you could put some plants! Of course you have to take care of them, and even if you don't have a green thumb, you can successfully grow plants thanks t...

Great and powerful sensor for everyone that wants to know the exact concentration of CO2(Carbon Dioxide) in the air.  This is the first CO2 sensor compatible with Arduino. The output voltage of the module falls as the concentration of the CO2 increases. The potentiometer onboard is designed to s...

This is a non-contact water / liquid level sensor for Arduino. It utilizes advanced signal processing technology by using a powerful chip (XKC-Y25-T12V) with high-speed operation capacity to achieve non-contact liquid level detection. No contact with liquid makes the module suitable for hazardou...
