The geeekus Analog Steam Sensor Module allows you to have a DC voltage output depending on the level of moisture detected across its sensor pads (dry state has a low value;when humidity on the face of this sensor rises, output voltage will increase). This basic sensor module can be used to detect the presence of steam, water, rainwater, moisture, vapour, etc. This steam sensor module can be connected to the GPIO of a 5V/3.3V microcontroller directly.
The geeekus Water Level Droplet Rainfall Sensor Detection Module is a high-quality sensor for Arduino, Raspberry Pi, micro:bit and most other 5V microcontrollers. This Water Level Sensor has many uses like measuring the water levels, monitoring a sump pit, detecting rainfall, and detecting leaks, etc.. The sensor has ten exposed traces, five are power traces and five are sense traces. The power and sense traces are not connected but become bridged when immersed in water.
The geeekus ULN2003 stepper motor driver board is a high quality compact module which allows you to control the 28BYJ-48 stepper motor. Because the 28BYJ-48 stepper motor consumes a significant amount of power, it cannot be controlled directly by a microcontroller like the Arduino. To control the motor, a driver IC such as the ULN2003 is required.
The geeekus Sound Sensor module is designed for measuring sound signals like voice, claps, snaps and knocks in your surroundings. It works through sound vibrations, which cause a plate inside the sensor to bend back and forth, producing a change in voltage that can be measured. Larger vibrations means higher values.
This protoboard is based on the ABRA-6 breadboard. If you have any projects that you wish to transfer onto a breadboard but worry on how to connect them, then this board simply does that conversion for you. The end user simply connects what they have on the breadboard to this protoboard and solder away.
This Infrared IR Wireless Remote Control Kit for Arduino consists of a infrared remote control with 17 function keys and a 38KHz infrared receiver module, with the capabiltiy to transmit distances of up to 5-8 meters.
The geeekus PIR (passive infrared motion) Pyroelectric micro sensor is designed to work with Arduino, Raspberry Pi, micro:bit and almost any other microcontroller. This geeekus sensor is based on the AM312, which also works on 3.3V and not just on 5V (like HC-SR501) which makes it perfect for ESP8266 devices without a 5V line. It is also less prone to false triggers due to Wi-Fi interference.
The geeekus DS1302 real time clock module is high quality RTC module with high accuracy that provides seconds, minutes, hours, day, date, month, and year information.
The geeekus MQ-2 Gas Vapor Sensor module is useful for gas leakage detection for home and industry. It is suitable for detecting H2, LPG, CH4, CO, Alcohol, Smoke or Propane. Due to its high sensitivity and fast response time, measurement can be taken as soon as possible. The sensitivity of the sensor can be adjusted by potentiometer.
