Detects sound that is greater than the ambient noise (adjustable sensitivity). Can operate from 3.3V to 5V.

Measure the brightness of ambient light with a 16-bit sensor.

PIR sensors allow you to sense motion, almost always used to detect whether a human has moved in or out of the sensors range. They are small, inexpensive, low-power, easy to use and don't wear out. For that reason they are commonly found in appliances and gadgets used in homes or businesses. They are often referred to as PIR, "Passive Infrared", "Pyroelectric", or "IR motion" sensors.

A simple flex sensor 2.2" in length. As the sensor is flexed, the resistance across the sensor increases. Patented technology by Spectra Symbol - they claim these sensors were used in the original Nintendo Power Glove. I love the Nintendo Power Glove. It’s so bad!

Weight Sensor Module is based on HX711, which is a precision 24-bit analog-to-digital convertor designed for weight scale and industrial control applications to interface directly with a bridge sensor. It not only has a few basic functions, but also contains high integration, fast response, immunity, and other features. This weight sensor lowers the cost of the electronic scale, and at the same time improving the performance and reliability. The input interface is compatible with Arduino I/O port. The output adopts compact terminal that makes the sensor easier to connect. It's the best choose for electronic enthusiast to do some tiny home scale.
