Capacitive touch sensor module for Arduino and other microcontroller projects
One side has a 9mm x 9mm capacitive touch area, and a TTP223 touch sensor IC on the reverse.
An LED indicates when the switch is touched, giving a digital. It can be set either a high or low output, and momentary or latching output by joining or not joining the A and B connections:
Soil hygrometer module with digital and analogue outputs for Arduino and other microcontroler projects
This module has a seperate 2 pronged moisture detector that is inserted into the soil and then connected to the comparitor board using the supplied link wires. It can give out a digital (High/Low) signal at a certain moisture level that can be set by adjusting the potentiometer on the board. There is also an analogue output to give you a more precise reading of the moisture level in the soil.
This PSU board is designed to fit directly on to a standard breadboard such as our BB400T and BB830. to give 2 power rails, 5V or 3.3V, Rail voltages are switch selectable. It can powered by 7-12V at the DC socket or 5V via the micro USB socket.
Alcahol Ethanol sensor module for Arduino and other microcontroller projects
A sensitive ethanol sensor will detect levels of alcahol in the air. The level of alcohol varies the output voltage. A comparator gives a digital output. When the ethanol level reaches a certain level, this can be set with the built in potentiometer.
Please note: this sensor needs to run for 24-48 hours before first time use
Methane gas sensor module for Arduino and other microcontroler projects
This module has a sensitive methane sensor that will detect levels of methane in the air. The sensor outputs a varying voltageon the analogue pindepending on the level of methane and it has a comparitor to give you a digital out at when the methane level reaches a certain level, this can be set with the built in potentiometer.
Please note, this sensor needs to warm up for 20 seconds before it will give a stable reading.
Carbon Monoxide sensor module for Arduino and other microcontroler projects
A Carbon Monoxide sensor detects CO in normal air conditions.
The resistance of the sensor changes with CO levels giving a varying voltage on the analogue pin. A comparator supplies a digital output when the CO level reaches a certain level, set with the built in potentiometer.
Please note, this sensor needs to run for 24-48 hours before first time use
Barometric pressure sensor module for Arduino and other microcontroller projects
This tiny module has a BMP180 precision pressure sensor soldered on to a GY-68 breakout board to make it easy to use this amazing sensor. The BMP180 will give you accurate pressure data via the standard I2C protocol making it simple to add to your project.
3 Axis accelerometer and gyroscope module for Arduino and other microcontroller projects
This module has an MPU-6050 accelerometer and gyroscope IC on a GY-521 breakout board to make it easy to use this amazing sensor. The MPU-6050 will give you accurate position and movement data via the standard I2C protocol making it simple to add to your project.
Infrared IR remote control and receiver kit for Arduino and other microcontroler projects
This kit comes with a simple battery powered infra red remote control, a matching IR receiver modual (KY-022) and a 5mm IR transmitter all working on at 38kHz. This kit can be combined with many other projects to add remote control to them.
Vibration switch module for Arduino and other microcontroler projects
This module is a switch that will detect small knocks and vibrations, it is more sensitive than the knock sensor (KY-031) so can be used in projects that need very slight movement to be detected. This switch will "make" when the module is moved.
Key switch module for Arduino and other microcontroler projects
This module has a smalltactile switch that is normaly open and will close when pressed, it has a resistor connected in series with the switch so it can be used directly with a digital input on an Arduino when powered by 5VDC.
Laser transmitter module for Arduino and other microcontroler projects
This module has a 650nm Red laser diode head with resistor. It will produce a focused red dot. Please use with caution and never look directly into the laser or point it into anyone elses eyes.
Photo interupter module for Arduino and other microcontroler projects
This module has an optical slot device and 2 resistors fitted. The sensor will detect if an object is blocking the light between the emitter and dector in the photo interupter and can triger a digital input in your microcontroler.
Temperature and humidity module for Arduino and other microcontroler projects
This module has a DHT11digital temperature and humidity sensor and a resistor. The DHT11 uses a thermister for the temperature sensing and a capacitive humidity sensor along with an internal IC to give a digital output with both temperature and humidity.
RGB full colour 5MM LED module for Arduino and other microcontroler projects
This module has a 5MM RGB LED that can be used to create virtually any colour by varying the intensity of the 3 colours by using the PWM output to each pin. Resistors will be needed to connect to an Arduino.
Mercury tilt switch module for Arduino and other microcontroler projects
This module has a small glass bead with a ball of mercury in it that will either make or break a contact if it is tilted. It also has a surface mount LED that can be connected to iluminate when the switch is activated.
Tilt switch module for Arduino and other microcontroler projects
This module has a tilt switch that is normaly open and will close when the module tilts, it has a resistor connected in series with the switch so it can be used directly with a digital input on an Arduino when powered by 5VDC.
