INTRODUCTION This is a photoelectric liquid level sensor that is operates using optical principles. The advantages of this are good sensitivity and no need for mechanical parts - meaning less calibration! The corrosion resistant probe is...

INTRODUCTION This non-contact liquid level switch can be triggered when the liquid level fall below the sensor attached to the outside surface of a non-metal container. Unlike traditional liquid level sensors, it does not need to be...

INTRODUCTION This framed LCD12864 Shield with LED backlight is compatible with most of Arduino controllers and supports English/Chinese/Picture display. With 5 analog extension pins and 8 digital pins, the LCD12864 Shield also integrates...

INTRODUCTION Particle pollution – PM10 and PM2.5 has become a hot issue in recent years. While the term PM is simple, PM itself is a relatively complex mixture with extremely small particles and liquid droplets that float around in the...

INTRODUCTION KnowFlow is designed for environmentalists who want to monitor water quality and get real time data. It can monitor 2 parameters with basic kit: pH and Electronic conductivities. The kit is based on Arduino, easy to change...

INTRODUCTION This IR kit provides a remote control capability to your project. SHIPPING LIST IR Remote Controller x1 IR Receiver Module x1 (SKU: DFR0094) Digital Cable x1

INTRODUCTION Say goodbye to messy cables and clueless plugging/unplugging! This Mega Sensor Shield V2.4 is a powerful expansion shield for Arduino Mega. It is large enough to carry up to 3 Xbee slots, 1 microSD slot and shield headers...

INTRODUCTION We can divide temperature measurement in to two types: contact and non-contact. Contact measurement can only accurately measure temperature when the testing object and the sensor reach thermal equilibrium. This can mean...

INTRODUCTION PT100 is suitable for most of the temperature measurement below 400°C, but usually the temperature of the household natural gas stove can reach over 800°C, and the temperature of the pottery kiln or high-power electric...

INTRODUCTION Gravity: I2C Digital Wattmeter is a high-resolution, high-precision, large-scale measurement module that can measure the voltage, current and power of various electronic modules and electrical equipment within 26V 8A, and...

INTRODUCTION This is an Arduino compatible fingerprint module. With the high speed DSP processor, it could also work with other serial device, like MSP430, 51, AVR, PIC, STM32, ARM and FPGA device. This fingerprint module could work...

INTRODUCTION This is a most powerful standard servo sized motor from DFRobot so far. The DF15RSMG equips with two pairs of the servo shells. One is a stardard shell with four M4 mounting holes. And the other one includes a shell with...
