Sensor & Modules

The DC Motor Speed ​​Controller allows the speed of a DC motor to be controlled using Pulse Width Modulated (PWM) DC voltage with a fully adjustable Duty Cycle from 10% to 100%. The motor speed controller can supply 8A continuous current to your DC motor or other DC load. The circuit also includes a 10A fuse, with a reverse power supply connection and control overvoltage protection function.

1602 16×2 Green Backlight Character LCD Display For Arduino is a basic 16 character by 2 lines Alphanumeric display. This LCD 16×2 Character LCD Display has Black text on Green background. Utilizes the extremely common HD44780 parallel interface chipset. Interface code is freely available. You will need a minimum of 6 general I/O pins to interface to this LCD screen. Includes LED backlight. Works in 4bit and 8 bit Mode.

This is 220v operated AC dimmer which can be used to control heater or ac motor speed with current capacity under 25 ampere.

RF modules are widely used in electronic design owing to the difficulty of designing radio circuitry. Good electronic radio design is notoriously complex because of the sensitivity of radio circuits and the accuracy of components and layouts required to achieve operation on a specific frequency.

This product is a 8-channel relay module board with LED indicators, It can be controlled by microcontrollers such as Arduino, AVR, PIC, ARM any other microcontroller operating at 5V.

The AD8232 Single Lead Heart Rate Monitor is a cost-effective board used to measure the electrical activity of the heart. This electrical activity can be charted as an ECG or Electrocardiogram and output as an analog reading. ECGs can be extremely noisy, the AD8232 Single Lead Heart Rate Monitor acts as an op-amp to help obtain a clear signal from the PR and QT Intervals easily. The AD8232 is an integrated signal conditioning block for ECG and other bio-potential measurement applications. It is designed to extract, amplify, and filter small bio-potential signals in the presence of noisy conditions, such as those created by motion or remote electrode placement.

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.

This module consists of a DHT11 digital humidity and temperature sensor and a 1 kΩ resistor.  The DHT11 uses an internal thermistor and a capacitive humidity sensor to determine environmental conditions, an internal chip is responsible for converting readings to a serial digital signal.

These temperature sensors work great with any microcontroller using any single digital pin. We can also connect multiple ones to the same pin. Each one has a unique 64 bits ID burn. It is useable with 3 to 5 volts systems. There is one downside of this sensor is they use the Dallas 1-wire protocol, and which is somewhat complex. This protocol requires a bunch of code to parse out the communication. When you are using this temperature sensor with a microcontroller put a 4.7K resistor to the sensing pin.

The ADXL335 is a small, thin, low power, complete 3-axis accelerometer with signal conditioned voltage outputs. The product measures acceleration with a minimum full-scale range of ±3 g. It can measure the static acceleration of gravity in tilt sensing applications, as well as dynamic acceleration resulting from motion, shock, or vibration.
