    Soil Moisture Sensor and Soil Detector Module Soil Moisture Test Soil Moisture Test Corrosion Resistance Probe for Arduino

    NPR 750.00

    This module is a soil moisture detector sensor module + it has corrosion resistance probe which are compatible with the Arduino. This soil moisture sensor can read the amount of the moisture present in the surrounding soil.This soil moisture arduino compatible sensor uses the two probe to pass the current through the soil, as if in the soil more water is present than that soil will conduct the electricity more easily like less resistance will be offered and if the soil is dry than that soil will offer more resistance and soil conduct electricity will be poor. This Moisture Sensor can be used to detect the moisture of soil or judge if there is water around the sensor, let the plants in your garden reach out for human help. They can be very to use, just insert it into the soil and then read it. With help of this sensor, it will be realizable to make the plant remind you. if there is requirement of water or not. This module requires input supply voltage of 3.3 – 5VDC and its working current is less than 20mA. This soil humidity detection module includes a potentiometer and soil moisture thresholds.

    LPG Gas Sensor (MQ6)

    NPR 550.00

    This Liquefied Petroleum Gas (LPG) sensor is suitable for sensing LPG (composed of mostly propane and butane) concentrations in the air. It can detect gas concentrations anywhere from 200 to 10000ppm. This sensor has a high sensitivity and fast response time. The sensor’s output is an analog resistance. The drive circuit is very simple; all you need to do is power the heater coil with 5V, add a load resistance, and connect the output to an ADC.

    Thyristor / Thermistor

    NPR 30.00

    Thyristor is a solid-state semiconductor device with four layers of alternating N and P-type material. It acts exclusively as a bistable switch, conducting when the gate receives a current trigger, and continuing to conduct while the voltage across the device is not reversed (forward-biased). It is one of the several controllable semi conductor devices that can act either like a switch, rectifier or as a voltage regulator.

    PIR Sensor HC-SR501

    NPR 250.00

    A passive infrared sensor (PIR sensor) is an electronic sensor that measures infrared (IR) light radiating from objects in its field of view. They are most often used in PIR-based motion detectors.

    For most of our Arduino projects that need to detect when a person has left or entered the area, or has approached, HC-SR501 PIR sensors are a great choice. They are low power and low cost, pretty rugged, have a wide lens range, easy to interface with and are insanely popular among hobbyists.

    HC-SR501 PIR sensor has three output pins VCC, Output and Ground as shown in the diagram below. It has a built-in voltage regulator so it can be powered by any DC voltage from 4.5 to 12 volts, typically 5V is used. Other than this, there are a couple options you have with your PIR.
