5Pcs Soil Hygrometer Humidity Detection Moisture Sensor For Arduino Description: This is a summary of the soil moisture sensor can be used to detect moisture, when the soil is dry, the module outputs a high level, whereas output low. Using this sensor make an automatic watering system, so that your garden plants without people to manage. Operating voltage: 3.3V~5V. Adjustable sensitivity (shown in blue digital potentiometer adjustment) Dual output mode,analog output more accurate. A fixed bolt hole for easy installation. With power indicator (red) and digital switching output indicator (green). Having LM393 comparator chip, stable. Panel PCB Dimension: 3cm x 1.5cm. Soil Probe Dimension: 6cm x 2cm. Cable Length: 21cm. VCC: 3.3V-5V. GND: GND. DO: digital output interface(0 and 1). AO: analog output interface. Instructions for Use: 1. Soil moisture module is most sensitive to the ambient humidity is generally used to detect the moisture content of the soil. 2. Module to reach the threshold value is set in the soil moisture, DO port output high, when the the soil humidity exceeds a set threshold value, the module D0 output low. 3. The digital output D0 can be connected directly with the microcontroller to detect high and low by the microcontroller to detect soil moisture. 4. The digital outputs DO shop relay module can directly drive the buzzer module, which can form a soil moisture alarm equipment. 5. Analog output AO and AD module connected through the AD converter, you can get more precise values of soil moisture. Package Included: 5 x Soil moisture detector module 5 x Probe 5 x 2P Jumper Cable

5Pcs Speed Measuring Sensor Counter Motor Test Groove Coupler Module For Arduino Application: Widely used in motor speed detection, pulse count, the position limit, etc.   Feature:   Using imported groove optical coupling sensor, width 5mm. It have the output state light, if output high level, the lights are off. if output low level,it on. If it covered,it will output high level;otherwise it output low level. Good signal and waveform, with strong driving ability for more than 15mA. The working voltage of 3.3V to 5V. Output: digital switch output (0 and 1). Equipped with a fixed bolt hole, easily install. Small board PCB size: 3.2 cm x 1.4 cm. Use the LM393 wide voltage comparer.   Specification:   The DO output interface can be directly connected to a micro-controller IO port, if there is a block detection sensor, such as the speed of the motor encoder can detect. DO modules can be connected to the relay, limit switch, and other functions, it can also with the active buzzer module, compose alarm.   Wiring specification: VCC Connect the positive 3.3 5 v power supply GND Connect power negative DO TTL switch signal output AO This module does not work Package included: 5 x Speed Measuring Sensor Module

5Pcs Jog Type Touch Sensor Module For Arduino Description: This is jog type capacitive touch switch sensor module based on a touch detection IC TTP223B. Normally, the output is low level(at mode of low power consumption). When the finger touch the corresponding location, output will be high(at quick speed mode). When the module do not be touched for 12 seconds, the mode would switch to low-power mode. It can be installed in the module, such as plastic, glass, non-metallic material surface. But not cover thin sheets(metal) on the surface of the module. Just touch the correct position, it can be hidden in walls, desktops and other parts to be buttons. Allows you to remove the troubles of conventional push-type buttons. Feature: Low power consumption Can replace the traditional key With four M2 screw holes, easy for operation Specification: Operating voltage: DC 2.0V ~ 5.5V VOH: VCC 0.8V VOL: VCC 0.3V Sink current: 8mA @ VCC = 3V, VOL = 0.6V Source current: -4mA @ VCC = 3V, VOH = 2.4V Response time: 220ms (at mode of low power consumption) and 60ms (at quick speed mode) Size: 24 x 24 x 7.2mm Package included: 5 x Capacitive jpg type touch sensor module
