Temperature & Humidity Sensor DHT 21 Digital Output
DHT21 Capacitive Digital Temperature & Humidity Sensor sensor is one of the commonest from the range of DHT temperature sensors and boasts a relatively high-temperature measurement accuracy of 0.5oC in 0.1oC steps with a relative humidity accuracy of +/- 3%. It has only 3 wires, including power and ground, meaning only one digital pin is required to interface it to a microcontroller. For Arduino development platforms the sensor is very well supported by the DHT library available from the Arduino Playground website.

Touch Switch Mirror For Lighting 12V 3A
Touch Control Sensor Switch for Mirror Light can be powered by simply supplying a 12VDC. It has a switch control function to light up LED lights from a single touch. The product is specially designed for smart light mirrors. It is suitable for the control of two mirror lights, single touch switch controls both the LED’s one after the other, which means on the first touch the LED connected with blue wire will glow. On the second touch, the LED connected with white wire will glow and on the third touch both the LED’s will glow together. The fourth touch switches off both the LEDs. The module has a feature to control the brightness of both the LED strips. The touch switch has a feature of backlight, according to this as the power gets supplied to the module the touch switch starts glowing white and whenever the LED is switched on the white Colour changes to blue. INPUT gets connected to the input 12VDC supply to power the module. OUTPUT gets connected to two LED strips. The positive wire(red coloured ) will be common for both LED strips and the other two negative wires(blue and white-coloured) will get connected with the negative of both the LED strips. The LED’s intensity can be controlled by touching continuously the touch switch, it goes from bright to dim then removing the finger and placing it again, it goes from dim to bright. Both the LED strip’s intensity can be altered, either when the single LED is glowing or while both the LEDs are glowing.

Water Flow Sensor Flow Meter Flow meter Counter YF-S201
Accurate flow measurement is an essential step both in the terms of qualitative and economic points of view. Flow meters have proven excellent devices for measuring water flow, and now it is very easy to build a water management system using the renowned water flow sensor YF-S201. For example you can make a robotic cocktail dispensing machine, and can use this sensors to accurately measure components like Soda, Water, etc.
YF-S201 1/2 inch Water Flow Sensor sits in line with the water line and contains a pinwheel sensor to measure how much water has moved through it. There is an integrated magnetic Hall-Effect sensor that outputs an electrical pulse with every revolution. YF-S201 1/2 inch water flow sensor has only three wires and it can be easily interfaced between any microcontroller and Arduino board. It requires only +5V Vcc and gives pulse output, the sensor needs to be tightly fitted between water pipeline.
