The ESP32-CAM is a WIFI + Bluetooth Development Card based on the ESP32 Chip, with the additional possibility of using a camera. It is ideal for a variety of loT applications.

The Kit Set of Torix Connectors is widely used in building wiring. By selecting the best insulation material, it is durable, corrosion free, anti-aging, pressure 4kv and against electric shock. It breaks the disadvantage of the traditional wiring method which is problematic in wiring, easy to leak, and easy to corrode.

Now the ESP8266 D1 Mini v3 is no longer alone! If you like WiFi communication, especially with ESP8266 chips, you can't miss this kit that includes several modules such as sensors, button, LED, Display, Relay, protoboard, among others. And you couldn't miss the respective ESP8266 D1 Mini v3 to be able to program in an Arduino environment and develop your wireless and IoT projects.

The imported PL2303HX controller can stabilize the flash at high speed. With a 500mA auto-recovery fuse for protection and two data transmission indicators that can monitor the data transfer status in real time. The entire board is coated with a high-quality transparent heat-shrinkable layer, rendering the PCB in a state of isolation from the outside, so that the board is not burned. Electrostatic package, ensures that the plate will not be damaged before use. Supports WIN7 system.

This ESP8285 ESP M2 Module provides easy-to-use WiFi for any UART port and is compatible with the HC-06 Bluetooth modules. If your project uses Bluetooth, it is very easy to convert it to WiFi. Using the integrated web interface, WIFI-UART communication can be configured for TCP or UDP sockets on any port.

Grove's capacitive humidity sensor (corrosion resistant) is a soil moisture sensor based on changes in capacitance. Compared to resistive sensors, capacitive sensors do not require direct exposure of metal electrodes, which can significantly reduce electrode erosion.

This is a small Force Sensitive Resistor . It has an Active Detection Area of 0.16 "(4mm) in Diameter. This FSR from Interlink Electronics varies its Resistance depending on how much Pressure is being applied to the Detection Area. The stronger the Force, the lower the Resistance. When there is no Pressure Applied to the FSR, its Resistance will be greater than 1MΩ, with the Total Pressure applied to the Resistance it will be 2.5kΩ Two Pins extend from the Bottom of the Sensor, making it friendly to the Breadboard. are simple to set up and great for detecting pressure.

The SparkFun Current Sensor Breakout is a High Precision Card that uses the ACS723 for Moderate AC and DC Current Detection Applications. The ACS723 Sensor uses a Hall Effect Sensor to Emit a Voltage relative to the Current that flows through the IP + and IP- Pins on the Board. The advantage of using a Hall Effect Sensor, specifically, is that the Circuit Being Detected and the Sensor Reading Circuit are Electrically Isolated, which means that although your Arduino is Operating at 5V, the Detected Circuit may be Operating at Higher DC or AC voltages.

This Kit integrates 10 Grove Modules and a Grove connection Shield on a single PCB board. All of these Modules and the Base Shield are already connected through the Wires on the PCB. This means that you only need to connect the Arduino Sensor Kit to the Arduino UNO or a Compatible Board (For example, SeeeduinoV4,2) and connect directly to a computer, then you can start programming and programming the Arduino with all sensors, actuators and OLED screens in the Arduino Sensor Kit.

Designed to facilitate the creation of IOT projects, the Arduino Oplà is based on a Arduino MKR WiFi 1010 , on which the Arduino wrapped in a plastic box. The kit includes a round OLED Display, along with Five Touch Buttons and Multiple Sensors to Monitor Air Pressure, Humidity, Light Intensity and Temperature. However, Additional Sensors must be simple to connect, like a PIR Sensor, which the Arduino also groups.

A Adjustable DC Power Module with 3~35VDC and 6A, with Display-LTC1871.

Using our muscles to control things is the way most of us are used to doing. We push buttons, pull levers, move joysticks ... but what if we could get the buttons, levers and joysticks out of the equation? This is the MyoWare Muscle Sensor , an all-in-one electromyography (EMG) sensor powered by Arduino from Advancer Technologies. The MyoWare Plate works by measuring the filtered and rectified electrical activity of a muscle, producing Volts depending on the amount of activity in the selected muscle, where Vs means the voltage of the power supply. It's very easy: place some electrodes (Not Included), read the tension and flex some muscles!

A Water Level Sensor 1/2Npt with 0-220V, from ProK.

The Reader of Capacitive Fingerprint is a Module of Fingerprint standard designed for Secondary Development, allows a Verification of Fingerprint Fast and Stable.

Based on a STM32F105R8 High Speed ​​Digital Processor, combined with high security commercial Fingerprint Algorithm and advanced semiconductor sensor, the capacitive fingerprint reader becomes a simple yet intelligent integration module, providing features such as registration digital printing, image processing, resource location, model generation and storage, fingerprint matching and research, etc.

The VMA214/RFM69HC Transceiver Module operates over a wide frequency range, including license exempt ISM (Industry Scientific and Medical) frequency bands 315, 433, 868 and 915MHz. All major RF communication parameters are programmable and most can be configured dynamically.
