Raindrops Detection Sensor Module

The Raindrops Detection sensor module is used for rain detection. It is also for measuring rainfall intensity. Rain sensor can be used for all kinds of weather monitoring and translated into output signals and AO.

This is JoyStick Module PS2 Breakout Sensor very similar to the ‘analog’ joysticks on PS2 (PlayStation 2) controllers. Directional movements are simply two potentiometers – one for each axis. Pots are ~10k each. This joystick also has a select button that is actuated when the joystick is press down.

With the help of this Joystick Module, you can measure position coordinates on the X and Y axis by moving the “hat”. It also contains a switch that is press-able by pushing the “hat”.It also contains a switch that is press-able by pushing the “hat” down. Similar to the XBOX controller.

The X and Y axes are two 10k potentiometers which control 2D movement by generating analog signals. When the module is in working mode, it will output two analog values, representing two directions. This module uses the 5V power supply, and value, when reading through analog input, would be about 2.5V, a value will increase with joystick movement and will go up till maximum 5V; the value will decrease when the joystick is moved in other direction till 0V.

Applications:

1.As square wave signal generator which generates a square wave signal

2. To provide a signal to the stepping motor driver

3. Adjustable pulse generation for chip use

4. Produce variable pulse signal, the control-related circuit (PWM dimming, speed)

Module Description:

Frequency is divided into three ranges:

1.XXX (no decimal point):the smallest unit is 1Hz,the range 1Hz-999Hz

2.XX.X (decimal point in ten): The minimum unit is 0.1Khz; the range of 0.1KHz-99.9KHz

3.X.X.X.(there is three decimal point): the smallest unit is 1Khz; the range 1KHz-150KHz

Frequency Display Example:

1.”100″ indicates that the PWM output pulse of 100Hz

2.”54.1″ indicates that the PWM output pulse of 54.1KHz

3.”1.2.4.” Indicates that the PWM pulse output 124KHz

4.Duty Cycle in the range:0 to 100

5. Three frequencies duty cycle is the same, all the parameters non-volatile

Features:

1. 2.54mm pin interface leads
2. Long service life and stable performance
3. Standard interface and electronic building blocks
4. Widely use in Arduino DIY projects
5. Cross rocker as a two-way 10K resistor, with the rocker in a different direction.

1 x JoyStick Module PS2 Breakout Sensor + Knob Hat

If you are wandering to build a device that detects temperature and humidity from the atmosphere, then This sensor is needed for you. you can Purchase this sensor from Robu.in at a reasonable price.

The DHT22 Digital Temperature and Humidity Sensor Module AM2302 is a basic, low-cost digital temperature and humidity sensor. It uses a capacitive humidity sensor and a thermistor to measure the surrounding air and spits out a digital signal on the data pin (no analog input pins needed).

It’s fairly simple to use but requires careful timing to grab data. The only real downside of this sensor is you can only get new data from it once every 2 seconds, so when using our library, sensor readings can be up to 2 seconds old.

Features :

1. High precision
2. Capacitive type
3. Full range temperature compensated
4. Relative humidity and temperature measurement
5. Calibrated digital signal
6. Outstanding long-term stability
7. Extra components not needed
8. Long transmission distance
9. Low power consumption
10. 4 pins packaged and fully interchangeable

Package Includes :

1 x DHT22 Digital Temperature and Humidity Sensor Module AM2302

This is TCRT 5000 Dual Channel Line Tracking sensor module.

This IR reflective sensor Module used TCRT5000 IR Sensor to detect color and distance. This sensor module consists of an IR transmitter & an IR receiver. IR Transmitter continuously emits IR signal which is then reflected by an obstacle and is then detected by the IR receiver.

TCRT5000 Infrared Reflective Sensor Module is often used in line following robots, object sorting Robots because this module can sense if a surface is white or black. The measuring distance range from 1mm to 8mm and the central point is about 2.5mm.

Application :

1. Meter pulse data sampling
2. Fax paper shredders detection
3. Obstacle detection
4. Black and white line detection

Features :

1. Designed with the reflected infrared sensor, indicator light.
2. Built in a potentiometer for sensitivity control.
3. On-board LM393 voltage comparator chip and infrared sensing probe TCRT5000L
4. Onboard signal output instructions, the output is the highly effective signal at the same time, the indicator lamp light output signal can be directly and single-chip microcomputer IO connection & middot
5. Signal detection sensitivity can adjust
6. Reserve all the way more circuits (P3 voltage drawn)
7. Using the TCRT5000 infrared reflection sensor
8. Output form: digital switch output (0 and 1)
9. A fixed bolt hole, convenient installation.

Package Includes :
