The LDR or Light-Dependent Resistor is a low-cost photosensitive element which is used both as smoke, flame, burglar detectors, photographic light meters, card reading systems, lighting controls for street lamps for several years and and other applications.
DHT11 is a compositional digital sensor for temperature and humidity. The sensor has the calibrated temperature and humidity digital signal output.
The Multipurpose IR Sensor is an add-on for your line follower as well as obstacle avoidance robot that allows it to identify lines or surrounding objects. It can be used extensively to avoidance car, line counts and track black and white lines, as well as on many other occasions.
PIR sensors make it possible to sense motion, which is almost always used to determine whether a human has entered or exited the sensor’s range. This sensoris high sensitivity, high reliability, ultra-low-voltage operating mode, widely used in various auto-sensing electrical equipment, especially for battery-powered automatic controlled products.
The LM35 is a high-precision semiconductor temperature sensor with a 10mV per degree Centigrade output. Unlike devices with outputs proportional to absolute temperature (in degrees Kelvin), there is no large offset voltage that must be removed in most applications.
Soil Moisture Sensor
This Moisture Sensor can be used to detect soil moisture or determine if water is present near the sensor, allowing your garden plants to seek human assistance. They’re simple to use; simply place it in the soil and read the results. It will be possible to make the plant remind you: “Hey, I’m thirsty right now, please give me some water” with the help of this sensor.

The rain sensor module is a simple rain detection tool. When a raindrop falls through the raining board, it can be used as a switch, as well as to measure rainfall intensity. The sensitivity can be adjusted using a potentiometer. All gizDuino boards are compatible with it.
