CJMCU Plant Watering Alarm Humidity Moisture Sensor

SKU: 2347

In stock

PKR  390
Description: plant watering alarm Durable and practical Top Sales Item Plant Watering Alarm Sensor This sensor will be silent when it?s dark and will restrict itself from making too much noise. This is a plant watering alarm - as simple as that. You put it into the soil near a plant and it emits a tiny chirp when the soil is dry, reminding you to water the plant. It uses capacitive humidity sensing as opposed to resistive humidity sensing, this means, it does not make an electric contact with the soil, avoiding electrode corrosion and soil electrolysis and resulting in better accuracy and longer battery life.

KY-039 5V Finger Detection Heartbeat Sensor Module Detector For Arduino

SKU: 2716

In stock

PKR  200
KY-039 5V Finger Detection Heartbeat Sensor Module Detector For Arduino 1.This project uses bright infrared (IR) LED and a phototransistor to detect the pulse of the finger, a red LED flashes with each pulse .Pulse monitor works as follows: The LED is the light side of the finger, and phototransistor on the other side of the finger, phototransistor used to obtain the flux emitted, when the blood pressure pulse by the finger when the resistance of the phototransistor will be slight changed. 2.Chosing a very high resistance resistor R1, because most of the light through the finger is absorbed,it is desirable phototransistor sensitive enough. Resistance can be selected by experiment to get the best results.The most important is to keep the shield stray light into the phototransistor. For home lighting that is particularly important because the lights at home mostly based 50HZ or 60HZ fluctuate, so faint heartbeat will add considerable noise.
