Thermographic Cameras
Creates images based on heat (infrared radiation) rather than visible light. Sees absolute temperature of every pixel.
Specs: range:-20°C to +400°C, resolution:80x60 to 640x480
Integrated Environmental Chips
Tiny chips that measure Temperature, Humidity, and Pressure in a single package.
Specs: precision:±0.5°C, ±2% RH, ±1hPa, interface:I2C/SPI
Air Quality (Particulate Matter)
Laser scattering sensors that count dust particles (PM2.5, PM10) to determine air purity.
Specs: target:PM1.0, PM2.5, PM10, method:Laser Scattering
