This basic piezo sensor from Measurement Specialties is often used for flex, touch, vibration, and shock measurements. A small AC and large voltage (up to +/-90V) is created when the film moves back and forth. A simple resistor should get the voltage down to ADC levels. Can also be used for impact s..
The HC-SR501 PIR Motion Detector Sensor Module is a pyroelectric device that detects motion by measuring changes in the infrared levels emitted by surrounding objects. This motion can be detected by checking for a high signal on a single I/O pin.
The module has an onboard pyroelectric sensor, con..
This is Plant Watering Alarm Alerter Humidity Moisture Sensor. It is inserted into the ground close to a plant, and when the soil is dry, it makes a tiny chirp to signal you to water the plant. It uses capacitive humidity sensing as opposed to resistive humidity sensing.
