Shunt resistor 10A
Shunt resistor 10A

The Shunt Resistor is a special type of resistor with small resistance which allows large currents to pass through it. This is useful for measuring the current in a circuit: due to the Ohm’s law and voltage drop on the shunt resistor, we can know exactly which current passes through it. For example, for this resistor whose maximum current is 10A, the voltage drop at that current will be exactly 75mV (0.075V). Using a precise ADC, we can accurately measure the current of our consumer or power source.

 

Max. current: 10A
Voltage drop for max. current: 75mV
Dimensions: 120mm x 25mm

PM2.5 dust sensor GP2Y1010AU0F
PM2.5 dust sensor GP2Y1010AU0F

The dust sensor inside has an infrared LED and an IR receptor. This allows it to detect even the smallest interruption of the light flux from the diodes to the detector and to register this as a dust particle. It is also effective in detecting other finer particles, such as those found in cigarette smoke. It gives an analog value as output, which you can connect to the analog input of a microcontroller and accurately measure air quality.

Out of stock GSM/GPRS module SIM800L
GSM/GPRS module SIM800L

SIM800 is a well-known chip for GSM / GPRS (2G mobile network) communication. Insert a SIM card, call, send SMS and connect to the Internet using a microcontroller. This breakout allows these connections in a simple way, it communicates with Arduino over a serial link. It is programmed using Arduino’s already finished libraries. Breakout even comes with a small wire antenna that will be sufficient for testing and use in areas where the signal is corresponding!

 

ESP32-WROOM-32D WiFi module
ESP32-WROOM-32D WiFi module

The ESP32 is a more advanced successor to the well-known ESP8266. It is a SoC (System on Chip) that can function as a standalone microcontroller and has everything you need on WiFi and Bluetooth 4.0 (BLE 4.0, low-energy) communication. With nearly 30 I / O pins and low power consumption, ESP32 will almost certainly be the leader in the Internet of Things for years to come.

The microcontroller itself works at a frequency of 160MHz (up to 240MHz), while the module has a built-in flash memory of 4MB. It has all the classic protocols like 4x SPI, 2x I2C, 4x UART, and there are many built-in peripherals like 18x 12-bit ADC, 2x 8-bit DAC, 10x capacitive touch GPIO, temperature sensor, SD card controller, Ethernet interface, PWM, etc. The list is really long. It should not be forgotten that this module has FCC certification and PCB trace antenna.

 

SoC: ESP32
CPU: Xtens 32-bit LX6, 160MHz to 240MHz
• Flash memory: 4MB
• RAM memory: 520kB
Exact module name: ESP-WROOM-32
• Number of pins: 38
Dimensions: 18 x 25.5 x 2.8 cm

Electromagnetic door lock
Electromagnetic door lock

Electromagnetic lock allows you to lock the door by a microcontroller or an external system. This one can hold up to 60kg with its electromagnet, which is just enough to when used with doors of the appropriate weight. Ideally, it should be used on smaller doors, windows and drawers. It is activated, that is “locked” when it is supplied current.

It consists of two parts, piece of an electromagnet and the metal. Comes with all necessary screws for installation.
