Photoresistor Light Sensor Module for Arduino
$3.24A photoresistor is a light-controlled variable resistor. The resistance of a photoresistor decreases with increasing incident light intensity; in other words, it exhibits photoconductivity. A photoresistor can be applied in light-sensitive detector circuits, and light-activated and dark-activated switching circuits
A photoresistor module makes it easy to use on breadboards and Arduino projects

Soil Moisture Sensor Module – Hygrometer Humidity Detector for Arduino Watering
$8.64A soil moisture sensor module is an electronic device used to measure the water content in soil. It works by measuring the electrical resistance of the soil, which changes with the amount of water present. The hygrometer humidity detector component of the module detects the relative humidity of the air, which can impact soil moisture levels. The module can be used with an Arduino microcontroller to create a smart watering system for plants. The system can use the data from the soil moisture sensor and hygrometer to determine when to water the plants and how much water to provide, ensuring optimal growing conditions.
