Sensors & Modules

Create your own portable power bank with the 5V 1A Power Bank Charger Module. This compact and powerful module provides reliable charging capabilities, multiple protection features, and easy integration into your DIY projects.

The A3144E Hall Effect Sensor is a compact and reliable magnetic field detection device. It integrates a Hall voltage generator, signal amplifier, Schmitt trigger, and open-collector output—all in a single chip. Designed for high precision, it’s ideal for contactless switch applications, speed detection, position sensing, and more.

ESP32-CAM is a WIFI+ Bluetooth dual-mode development board that uses PCB on-board antennas and cores based on ESP32 chips. It can work independently as a minimum system.ESP integrates WiFi, traditional Bluetooth, and BLE Beacon, with 2 high-performance 32-bit LX6 CPUs, 7-stage pipeline architecture, main frequency adjustment range 80MHz to 240MHz, on-chip sensor, Hall sensor, temperature sensor, etc. Fully compliant with WiFi 802.11b/g/n/e/i and Bluetooth 4.2 standards, it can be used as a master mode to build an independent network controller, or as a slave to other hosts MCUs to add networking capabilities to existing devices.ESP32-CAM can be widely used in various IoT applications. It is suitable for home smart devices, industrial wireless control, wireless monitoring, QR wireless identification, wireless positioning system signals, and other IoT applications. It is an ideal solution for IoT applications.

The ESP32-CAM is a versatile and compact dual-mode Wi-Fi and Bluetooth development board, ideal for IoT applications. Featuring onboard antennas and cores based on the powerful ESP32 chip, this module supports both Wi-Fi (802.11b/g/n) and Bluetooth (BR/EDR, BLE) communication, making it perfect for a wide range of smart home, industrial control, and wireless monitoring projects.

The HC-SR04 Ultrasonic Sensor offers reliable and accurate non-contact distance measurements in a range of 2cm to 400cm (1” to 13ft). It uses sonar technology to determine the distance to an object, providing excellent performance even in varying environmental conditions.

The Obstacle Detector sensor module is perfectly adaptable to the environment light, IR Object Avoidance Sensor has a pair of infrared transmitting and receiving tubes; transmitting tube emits infrared in a certain frequency, when detecting direction meets with obstacles(reflecting surface), reflected infrared will be received by the receiving tube; after the comparator circuit processing, the green indicator will light up, at the same time signal output interface to output digital signal(1 low-level signal). Users can adjust the detection distance through the potentiometer knob, effective distance range 2~30cm and working voltage is 3.3V to 5V. The Obstacle Avoidance module LM393 can be widely used in robot obstacle avoidance, obstacle avoidance car, line count, black and white line tracking, and so on many occasions.
