45 Sensors in 1 Sensor Kit for Arduino and Raspberry Pi Projects
$48.60This sensor kit consists of 45 sensor modules that can be used in your Arduino and Raspberry Pi projects.
-
5mm Infrared LED Sender
$1.08LEDs with invisible light. Use these to light up a night vision camera, or to send IR pulses to an IR receiver.

DHT11 Temperature and Humidity Sensor
$5.40The DHT11 is a basic, ultra low-cost digital temperature and humidity sensor. It uses a capacitive humidity sensor and a thermistor to measure the surrounding air, and spits out a digital signal on the data pin (no analog input pins needed). Its fairly simple to use, but requires careful timing to grab data.

DHT11 Temperature and Humidity Sensor Module
$8.64The DHT11 is a relatively cheap sensor for measuring temperature and humidity.

DHT22 Temperature and Humidity Sensor
$14.04DHT22 is a basic, low-cost digital temperature and humidity sensor. It uses a capacitive humidity sensor and a thermistor to measure the surrounding air, and spits out a digital signal on the data pin (no analog input pins needed). It’s fairly simple to use, but requires careful timing to grab data. The only real downside of this sensor is you can only get new data from it once every 2 seconds, so when using our library, sensor readings can be up to 2 seconds old.

It uses a capacitive humidity sensor and a thermistor to measure the surrounding air, and spits out a digital signal on the data pin (no analog input pins needed). It’s fairly simple to use, but requires careful timing to grab data. The only real downside of this sensor is you can only get new data from it once every 2 seconds, so when using our library, sensor readings can be up to 2 seconds old.

Infrared LED Receiver Diode
$1.08This is a very simple, clear infrared LED. These devices operate between 940-950nm and work well for generic IR systems including remote control and touch-less object sensing.

Infrared Remote Control Module for Arduino
$9.72NEC type infrared controller (Arduino Library available)
HX1838 Receiver and relevant base board

Integration Ultrasonic Transceiver
$3.24The Integration Ultrasonic Transceiver is a device used for measuring distance and detecting objects using ultrasound. It works by emitting an ultrasonic pulse and measuring the time it takes for the pulse to bounce back from an object, allowing the distance to be calculated. The ultrasonic transceiver is typically used in applications such as distance sensing, object detection, and flow measurement. It has a compact design, making it suitable for use in a variety of projects, including robotics, automation, and instrumentation

Light Sensitive Photo Resistor
$0.54A photo cell (also called a photo resistor, photo detector, CdS or photoconductive cell) allow you to detect light. Its resistance depends on the amount of light it is exposed to. These little sensors make great ambient light triggers (when light in the room turns on, do something).

Photoresistor Light Sensor Module for Arduino
$3.24A photoresistor is a light-controlled variable resistor. The resistance of a photoresistor decreases with increasing incident light intensity; in other words, it exhibits photoconductivity. A photoresistor can be applied in light-sensitive detector circuits, and light-activated and dark-activated switching circuits
A photoresistor module makes it easy to use on breadboards and Arduino projects
