Infra Red Sensors
Vishay has a lot of light sensors out there, and this is a nice simple lux sensor that's easy to add to any microcontroller. Most light sensors just give you a number for brighter/darker ambient lighting.
Sensirion Temperature/Humidity sensors are some of the finest & highest-accuracy devices you can get. The SHT41 sensor is the fourth generation of I2C temperature and humidity sensor from Sensirion.
