A 433MHz RF wireless receiver and transmitter module is a pair of electronic components that enable wireless communication between devices using radio frequencies in the 433MHz frequency band. Here's a breakdown of these modules:RF Wireless Receiver Module:
The RF wireless receiver module is design..
The
Analog pH Sensor Kit is specially designed for Arduino controllers and
has a built-in simple, convenient, and practical connection and
features. It has an LED that works as the Power Indicator, a BNC
connector, and a PH2.0 sensor interface. To use it, just connect the pH
sensor with the BNC..
HX711 features dual-channel 24 Bit Precision A/D Weight Pressure Sensor Load Cell Amplifier which is available in a small breakout board. The board has pinouts for the microcontroller and the Load cell in two different directions for the ease of interfacing. It can be interfaced with any micro..
The eye–blink sensor works by illuminating the eye and eyelid area with infrared light, then monitoring the changes in the reflected light using a photo-transistor and differentiator circuit. The exact functionality depends greatly on the positioning and aiming of the emitter and..
This is a multipurpose infrared sensor which can be used for obstacle sensing, fire detection, line sensing, etc and also as an encoder sensor. The sensor provides a digital output. The sensor outputs a logic one(+5V) at the digital output when an object is placed in front of the sensor and a logic ..
Light Dependent Resistor is a very small light sensor. A LDR photocell changes resistance depending on the amount of light it is exposed to. These little sensors make great ambient light triggers (when light in the room turns on, do something, or vice-versa).Features:
Coated with epoxy
Good reliab..

This LM393 Photosensitive Light-Dependent Control Sensor LDR Module is using a high-quality LM393 voltage comparator. Easy to install using the sensitive type photosensitive resistance sensor the comparator output signal gives a clean and good waveform.Driving ability is 15mA with the adjustable pot..
MAX30100 is an integrated pulse oximeter and heart-rate monitor
sensor solution. It’s an optical sensor that derives its readings from
emitting two wavelengths of light from two LEDs – a red and an infrared
one – then measuring the absorbance of pulsing blood through a
photodetector. This pa..
MQ-135 Air quality and hazardous gas detection sensor module for projects Sensitive material MQ135 gas sensor is used in clean air low conductivity tin oxide (SnO2). When the sensor is kept in their environment. In the polluting gases , the conductivity sensor with increasing air pollution in g..
High sensitive passive infrared motion sensor with stable digital output.
PIR sensors allow you to sense movement (motion), almost always used to detect whether a human has moved in or out of the sensors range.
They are small in size, inexpensive, low-power consuming, easy to use. For this reason ..
This is the R307 Optical Fingerprint
Reader Sensor Module. R307 fingerprint module is a fingerprint sensor
with a TTL UART interface for direct connections to micro-controller UART
or to PC through MAX232 / USB-Serial adapter. The user can store the
fingerprint data in the module and can con..
