or "IR motion" sensors

This enables theuse of current limiting resistors to interface inputs to voltages in excess of VCC

Depending on your setup and what mode your system is in

Temperature & Humidity Sensor Module (DHT22) is low-cost digital temperature and humidity sensor

Three 16-bit analog-to-digital converters (ADCs) for digitizing the gyroscope outputs

Infrared Proximity Sensor(5 V-36 V) Omron Rotary Encoder or "IR motion" sensorsIntroduction: The Infrared Proximity Sensor (E18 D80NK) is a digital proximity sensor uses an infrared LED and receiver to determine the presence of an object within a specific distance. These make great obstacle detectors and can also be used as an optical gate or in positioning applications where stopping at certain distance is needed. Mounting this sensor is quite easy it has a long threaded body allowing for a considerable adjustment. The sensor
