The PIR (Passive Infra-Red) Sensor HC-SR501 is a pyroelectric device that detects motion by measuring changes in the infrared levels emitted by surrounding objects. This motion can be detected by checking for a high signal on a single I/O pin.

Module provides an optimized circuit that will detect motion up to 6 metres away and can be used in burglar alarms and access control systems.


The PIR sensor and Fresnel lens are fitted onto the the PCB. This enables the board to be mounted inside a case with the detecting lens protruding outwards, whilst still allowing easy access to the controls inside the case.

Product Details:

This is an infrared based sensor array which can be used in advanced line following and grid navigation robots. The array has 4 individual sensors placed next to each other. Each sensor has its own digital output and can sense the presence of a line and indicate it with a 5V logic output. On reading the the digital state of the eight sensors, the user can not only detect the line but also get to know how far the center of the robot is from the line. When all sensors sense the line, the robot is on an intersection.

Features:

• Uses 4 sensors for best resolution.
• Great useful in building fast line following and grid navigating robots.
• Comes with easy to use digital outputs that can be connected directly to microcontrollers.
• The array has mounting holes of 3mm diameter for easy mounting 

Specification:

• The working current, try to choose more than 1 a power supply
• The detection distance: 1 mm and 60 cm adjustable, the closer distance performance more stable, white reflection furthest distance

Additional Information:

• Item Code: array-4-way

Product Details:

The proximity switch is a high-frequency oscillation type, which sends a detection signal quickly, without pressure, no pressure, without a spark, to drive the relay or logic gate. It has high sensitivity, fast frequency response, high repeatability, Short, the output power is large, the anti-jamming performance is good, the working stability is reliable, the service life is long and so on.

MPR121 Breakout Board

• Capacitive touch sensor controller
• Communication Protocol: I2C
• Gives you 12 capacitive touch inputs and 1 virtual input
• Features eight LED driving pins (When these pins are not configured as capacitive inputs, they may be used to drive LEDs)
• Adjustable I2C Address via 4 jumpers on the bottom of the board. All jumpers are set (closed) by default. An address jumper ties the ADD pin to ground, meaning the default I2C address of the chip will be 0x5A. If you need to change the address of the chip (by shorting ADD to a different pin), make sure you open the jumper first. Jumpers also connect SDA, SCL and the interrupt pin to 10k pull-up resistors. If you don''t require the pull-up resistors you can open the jumpers by cutting the trace connecting them.
• Low-supply voltage mode (1.71-2.75VDC) activated by removing the 0.1uf capacitor between VREG and ground.
• Add up to 12 capacitive touch pads with this easy to use 12-channel capacitive touch sensor breakout board. Turn any item into a touch sensor!
