Light Intensity Module BH1750 for Arduino & Other
This is a BH1750 light intensity sensor breakout board with a 16 bit AD converter built-in which can directly output a digital signal, there is no need for complicated calculations. This is a more acurate and easier to use version of the simple LDR which only outputs a voltage that needs to be calculated in order to obtain meaningful data

Switches & Connectors
limit switch Leaf Switch Push button Toggle Micro Tact
This Single Pole Double Throw (SPDT) is a micro switch that needs a very less amount of force to operate. They are very reliable, fast and efficient to use. A microswitch is also known as a miniature snap-action switch. This switch is in a Normally closed configuration by default and it will return to the original setting upon releasing the leaver.

Microwave Doppler HB100 Radar Wireless Motion Sensor
HB100 is the use of microwave Doppler radar module (Doppler Radar) design principles of the microwave detector moving objects, mainly used in automatic door control switches, security systems, ATM ATM automated video control systems, automatic train signal, etc. place. HB100 is the standard 10.525GHz microwave Doppler radar detector, the detection method compared with other detection methods have the following advantages: 1, non-contact detection; 2, independent of temperature, humidity, noise, air, dust, light other effects, suitable for harsh environments; 3, anti-RF interference ability; 4, the output power is small, constitute a hazard to humans; 5, distance: more than 20 meters detection range.5,Doppler Principle: Doppler theory based on time, when radio waves encounter an object in the moving process will be reflected when the waves, the frequency of the reflected wave will hit the object with the movement to change state. If the radio waves encounter an object position is fixed, then the reflected wave frequency and transmitting frequency waves should be equal. If the object moves toward the launch, then the reflected waves will be compressed, that will increase the frequency of the reflected wave; otherwise the reflected wave’s frequency decreases
