I2C pin header and an I2C connection are both included on the PCF8574 IO Expansion Board. Theref..
This is a breakout board/Prototype Board for PCF8591 IC. The PCF8591 is a single-chip, single‑supply low‑power 8‑bit CMOS data acquisition device with four analog inputs, one analog output, and a serial I²C‑bus interface. Three address pins A0, A1, and A2 are used for programming the hardware addres..
The PH sensor measures the hydrogen-ion activity in water-based solutions, we usually use it to measure the PH of a liquid.
It is widely used in the chemical industry, the pharmaceutical industry, the dye industry, and scientific research where acidity and alkalinity testing is required.

Photoresistor also is known as LDR(Light Dependent Resistor) as the names imply, changes the resistance with the variation in the amount of light. This particular photoresistor has a resistance of 5-10k Ohm in light and about 500k Ohm resistance in the dark.
The LDR 5mm Light-Dependent Resi..
The PicoBoard incorporates a light sensor, sound sensor, a button, and a slider, as well as 4 additional inputs that can sense electrical resistance via included cables.Designed for educators and beginners, the PicoBoard is a good way to get into the very basics of programming and reading sensors.Th..
This basic piezo sensor from Measurement Specialties is often used for flex, touch, vibration, and shock measurements. A small AC and large voltage (up to +/-90V) is created when the film moves back and forth. A simple resistor should get the voltage down to ADC levels. Can also be used for impact s..
The HC-SR501 PIR Motion Detector Sensor Module is a pyroelectric device that detects motion by measuring changes in the infrared levels emitted by surrounding objects. This motion can be detected by checking for a high signal on a single I/O pin.
The module has an onboard pyroelectric sensor, con..
This is PL2303 PL2303HX USB To TTL(Serial) Converter Module – 5 Pin. Adopt imported controller RS232 TTL, which can stabilize the flash with high-speed 500mA self-recovery fuse for protection.
Two data transmission indicator can monitor data transfer status in real-time. Reserve 3.3V and 5V pin i..
This is Plant Watering Alarm Alerter Humidity Moisture Sensor. It is inserted into the ground close to a plant, and when the soil is dry, it makes a tiny chirp to signal you to water the plant. It uses capacitive humidity sensing as opposed to resistive humidity sensing.
The alarm level can be se..
