Digital Vibration Sensor Module

This is a simple-to-use Carbon Monoxide (CO) sensorsuitable for sensing CO concentrations in the air. The MQ-7 can detect CO-gas concentrations anywhere from 20 to 2000ppm. 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 5Vadd a load resistanceand connect the output to an ADC. This sensor comes in a package similar to our MQ-3 alcohol sensorand can be used with the breakout board below Here at Mikroelectron.comWe give high sensitivity and fast responsive carbon monoxide sensor mq-7Buy @JD5.00 online.carbon monoxide sensor - mq-7

Description: Dual Axis XY Joystick KY023 KY-023 JOY-STICK Dual Axis XY Joyst-icks 5 Pin 5V Module PS2 Joy-stick Control Lever Sensor Game Controller With Cables For Arduino Electronics Circuitry & Parts Analog joystick-like devices used for example Controllers PlayStation second detection directions of traffic is carried by two potentiometers – one (4.7 k Ω ) on each axle. The device also has a button activated by pressing the knob . To operate the device, all you need is a microcontroller with an analog-to-digital converter (analog input in Arduino ). The location information of the knob is transmitted through an analog signal, in which the voltage corresponds to the given position. Each axis has a separate analogue output. The state of the button is detected by a digital output which, when switched on, becomes low. 1. Input voltage range: DC 3.3V to 5V 2. Output signal: the module has two-way analog output and a digital output interface, the output value corresponding to (X, Y) bi-axial offset, the type of analog; keys that the user press, the Z axis is a push switch read as digital input. 3. Arduino controller can be programmed, the sensor expansion board plug, complete with creative remote interactive works. 4. Cross joystick is a bi-directional 10K resistor, with the rocker in different directions, the resistance should be changed by moving the lever. This module uses 5V power supply, the original state of X, Y read voltage of 2.5V or so, when pressed with the arrow direction, the read voltage value increases with the maximum to 5V, voltage decreases while move lever in opposite direction, The minimum is 0V. You have to use 2 analog inputs of MCU to read (X Y) the analog output of this module, the switch is a button which you may use with a digital input pin of your Micro Controller eg. Arduino, Raspberry Pi, Orange Pi, NodeMCU, ESP32, ARM AVR development boards. Features: Two independent Potentiometer: one for each axis ( X and Y) Auto return to center position

This is a simple-to-use liquefied petroleum gas (LPG) sensorsuitable for sensing  LPG (composed of mostly propane and butane) concentrations in the air. The MQ-6 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 hea...
