Our environmental conditions can have a major impact on our well-being, comfort, and output. Sensirion’s sensor resolutions deliver comprehensive and reliable data on key parameters including humidity, temperature, volatile organic compounds (VOCs), particulate matter (PM2.5), and CO2. Environmental Sensing proposes new possibilities to create smarter devices that increase our comfort and happiness while also improving energy efficiency in a number of applications.
Breathe easy with the SGP30 Multi-Pixel Gas Sensor, a fully integrated MOX gas sensor. This is a very fine air quality sensor from the sensor experts at Sensirion, with I2C interfacing and fully calibrated output signals with a typical accuracy of 15% within measured values. The SGP combines multiple metal-oxide sensing elements on one chip to provide more detailed air quality signals.
The Passive Infrared Sensor (PIR) sensor module is used for motion detection. It can be used as motion detector for security systems or robotics. It works on 5V DC and gives TTL output which can be directly given to microcontroller or to relay through a transistor.It consists of pyroelectric sensor and fresnel lens that detects motion by measuring change in the infrared levels emitted by the objects. It can detect motion up to 20ft. This module is very sensitive to change in infrared levels subjected by human movement.
