Vibration Sensor Module
NPR 350.00The vibration sensor module based on the vibration sensor SW-420 and Comparator LM393 is used to detect vibrations. The threshold can adjust using an on-board potentiometer. During no vibration, the sensor provides Logic Low and when the vibration is detected, the sensor provides Logic High.

VL53L0X TIME OF FLIGHT DISTANCE SENSOR – 30 TO 1000MM GY-530
NPR 1,200.00The GY-530 sensor has the VL53L0X sensor on board, with power management IC on board, the module can accept power arrange from 2.8V to 5V.
The VL53L0X is a new generation Time-of-Flight (ToF) laser-ranging module housed in the smallest package on the market today, providing accurate distance measurement whatever the target reflectances unlike conventional technologies. It can measure absolute distances up to 2m, setting a new benchmark in ranging performance levels, opening the door to various new applications.
The VL53L0X integrates a leading-edge SPAD array (Single Photon Avalanche Diodes) and embeds ST’s second generation FlightSenseTM patented technology.
The VL53L0X’s 940nm VCSEL emitter (Vertical Cavity Surface-Emitting Laser), is totally invisible to the human eye, coupled with internal physical infrared filters, it enables longer ranging distance, higher immunity to ambient light and better robustness to cover-glass optical cross-talk. -
Water Flow Sensor YF-S201
NPR 680.00This sensor sits in line with your water line and contains a pinwheel sensor to measure how much liquid has moved through it. There’s an integrated magnetic hall effect sensor that outputs an electrical pulse with every revolution. The hall effect sensor is sealed from the water pipe and allows the sensor to stay safe and dry.

Water level sensor (vertical)
NPR 550.00A float switch is a device used to sense the level of liquid within a tank. Products can be used for drinking fountains, water heaters, solar, air conditioners, humidifiers, bathroom equipment, vending machines, etc. This is a mini float switch. Contains no mercury.

Water Sensor
NPR 449.00Water Level Sensor is easy-to-use, cost effective high level/drop recognition sensor, which is obtained by having a series of parallel wires exposed traces measured droplets/water volume in order to determine the water level.

Waterproof Temperature Sensor (DS18B20)
NPR 700.00This sealed anti-rust digital temperature probe lets you precisely measure temperatures in wet environments with a simple 1-Wire interface. The DS18B20 provides 9 to 12-bit (configurable) temperature readings, so that only one wire (and ground) needs to be connected from a central microprocessor.

Waterproof ultrasonic sensor
NPR 890.00Take your sonar outside – great for all weather robots! The XL-MaxSonar-WRMA1 ignores smaller targets and only reports the range to target with the largest acoustic return. This is our most advanced weather resistant sensor designed for target detection and ranging outdoors or in tank or bin applications.

There are two types of reed switches: “normally open” reed switches and “normally closed” reed switches. The metal reeds on a normally open switch stay open when there is no magnet near the switch. In the presence of a magnetic field, the contacts of a normally-open reed switch will close. A normally-closed reed switch is closed when it is not near a magnet; as a magnet is brought close to it, a normally-closed switch will open

Wireless TXRX – ESP8266 (Serial Wireless Module)
NPR 800.00In terms of the form factor, it looks a lot like the nRF24L01 2.4G RF transceiver. This is a serial module with a built-in TCP/IP stack, so you can use it standalone but you will be likely limited. You need a FTDI to connect this module to your computer, and start communicating with it. FTDI is a common name for USB-to-TTL (or serial) converter.

Zener diode 2.4 volts
NPR 5.00A Zener diode is a particular type of diode that, unlike a normal one, allows current to flow not only from its anode to its cathode, but also in the reverse direction, when the Zener voltage is reached. Zener diodes have a highly doped p-n junction.
Zener diodes are used for voltage regulation, as reference elements, surge suppressors, and in switching applications and clipper circuits.
