DHT22 Digital Temperature and Humidity Sensor; Temperature and Humidity Module AM2302

The DHT22 ( RHT03 ) 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). Its fairly simple to use, but requires careful timing to grab data. Read more about DHT22 Digital Temperature and Humidity Sensor; Temperature and Humidity Module AM2302[…]

Hall Current Sensor Module ACS712 5A model

The device consists of a precise, low-offset, linear Hall circuit with a copper conduction path located near the surface of the die. Applied current flowing through this copper conduction path generates a magnetic field which the Hall IC converts into a proportional voltage. The current sensor chips: ACS712ELC-05B; Pin 5V power supply, on-board power indicator; Read more about Hall Current Sensor Module ACS712 5A model[…]
