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.

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.

PIR Motion Sensor Module – SR501
$6.48The PIR Motion Sensor Module – SR501 is a device used to detect motion in a room or area. It operates by using a passive infrared sensor to detect changes in the infrared radiation levels in its field of view, indicating the presence of a moving object. The module is small and compact, making it suitable for a range of applications, such as home automation, security systems, and robotics. The module outputs a digital signal, making it easy to interface with microcontrollers and other electronics.
