Contact & Proximity

This is a basic RFID tag used for presence sensing, Aceess Control, Contactless transmission of data and supplies energy with no battery needed etc. Operating frequency is 125KHz and Data transfer speed is 106 kbit/s. These tags come with a unique 32-bit ID and are not re-programmable. Card is blan..

This is 125K RFID Tag which uses RFID technology for sensing and identifying tagged objects (and people) for access control, automation, and a whole range of different applications. Operating on a frequency of 125kHz, these tokens are all pre-programmed with unique ID numbers written on the back o..

Digital Capacitive Touch Switch Module is based on TTP223B. Normally, it outputs low and keeps at low power state. When a touch is sensed on the circular marked region, it outputs high and switch to the quick response state. When not being touched for 12 seconds, it switches to low power state again..

Hall Effect Sensor module detects magnetic field and can be used as a digital switch to turn on/off in the presence of a magnetic field. If no magnetic field is present, the signal line of the sensor is HIGH. If a magnetic field is presented to the sensor, the signal line goes LOW, at the same time ..

Ultrasonic Distance Sensor is used to measure distance to the nearest obstacle and generally used for Obstacle avoidance robots. The sensor detects obstacles between 2CM to 4M while providing precise and stable non-contact distance measurements with very high accuracy. It can be easily interfaced to..

Pulse Sensor is a low cost, small size a plug-and-play heart rate sensor that can be used to incorporate live heart-rate detection data. The module has amplification and noise cancellation circuitry to the hardware and is noticeably faster and easier to get reliable pulse readings. The size is sma..

This is a slotted Opto isolator module (MOC7811 or compatible), with an IR transmitter and a photodiode mounted inside. The module performs non-contact object sensing which is normally used as positional sensor switch (limit switch) or as Position Encoder sensors used to find position of the wheel. ..

RC522 - RFID Reader / Writer 13.56MHz with Cards Kit includes a 13.56MHz RF reader cum writer module that uses an RC522 IC and two S50 RFID cards. The MF RC522 is a highly integrated transmission module for contact-less communication at 13.56 MHz. RC522 supports ISO 14443A/MIFARE mode. RC522 - RFI..

Reed Switch Module (KY-025) is a small electrical switch operated by an applied magnetic field, commonly used as proximity sensor. The module has both digital and analog outputs. A trimmer is used to calibrate the sensitivity of the sensor. The switch is normally open and the output of the switch is..

This is a digital capacitive touch switch based on TTP223B touch-sensing IC. The module works as a switch and replaces a traditional push-type key. Module generally outputs low and keeps at low power state. When a touch is sensed on the circular marked region, it outputs high and switches to the qu..
