DHT22 - Digital temperature and humidity sensor

The DHT22 is a simple, low-cost digital temperature and humidity sensor. It uses a capacitive humidity sensor and a thermistor to measure the ambient air and outputs a digital signal on the data pins (no analogue input pins required). It is relatively simple to use, but requires careful timing to capture data. The only real disadvantage of this sensor is that you can only get new data from it every 2 seconds, so the sensor readings can be up to 2 seconds old.Technical data Operating voltage: 3 - 5V2.5mA maximum current consumption during data requestMeasuring ranges:Humidity: 0-100%, ±2-5% accuracyTemperature: -40 - +80°C, ±0.5°C Accuracy0.5 Hz sampling rate (once every 2 seconds)Dimensions approx. 27 x 59 x 13.5 mm

4-channel infrared receiver incl. remote control

This 4-channel infrared receiver can decode the infrared commands sent by the supplied remote control and outputs the corresponding high levels for the individual channels via the pin header. How it works By default, LOW levels are present on the pin header of the receiver module. If one of the channel buttons (CH 1-4) on the remote control is pressed, the corresponding output (OUT 1-4) changes from LOW to HIGH and the corresponding LED (H 1-4) on the receiver board lights up for as long as the channel button on the remote control is pressed. When the red power button on the remote control is pressed, all outputs on the receiver board change from LOW to HIGH and all LEDs light up as long as the button on the remote control is pressed. Technical data receiver board Operating voltage: 3-5V Connections via pin header (RM 2.54) VCC: Power supply input GND: Ground OUT1: Output channel 1 OUT2: Output channel 2 OUT3: Output channel 3 OUT4: Output channel 4 4 status LEDs for the individual outputs Dimensions: 38 x 29 mm 2 PCB holes for mounting Technical data remote control Operating voltage: 3V via lithium battery CR2025 Range: 5 - 8 metres Dimensions: 85.5 x 39.5 mm Scope of delivery Receiver board Infrared remote control incl. battery
