DEBO TEMP HUM developer boards - Temperature and Humidity Sensor, SHT31-D
This sensor uses I2C-adress 0x44 or 0x45. It can measure relative moisture with +- 2 % and has an accuracy of +- 0.3°C
GRV LIGHT SENSE Arduino - Grove Light Sensor, GL5528
The Grove - Light sensor module uses GL5528 photoresistor(light dependent resistor) to detect the intensity of light in the environment. The resistance of photoresistor decreases when the intensity of light increases. A dual OpAmp chip LM358 on board produces voltage corresponding to intensity of light(i.e based on resistance value). The output signal from this module will be HIGH in bright light and LOW in the dark.
This module can be used to build a light controlled switch i.e switch off lights during day time and switch on lights during night time.

GRV WATER SENS Arduino - Grove water sensor
Grove - Water Sensor detects the presence of water using exposed PCB traces. The sensor is made up of interlaced traces of Ground and Sensor signals. The sensor traces are weakly pulled up using 1 M O resistor. The resistor will pull the sensor trace value high until a drop of water shorts the sensor trace to the ground trace. This circuit will work with digital I/O pins of Arduino or you can use it with the analog pins to detect the amount of water induced contact between the grounded and sensor traces.
Applications
• Rainfall detection
• Liquid leakage
• Tank overflow detection
Features
• Grove compatible interface
• Low power consumption
• High sensitivity
GRV LOUDNESS Arduino - Grove Volume Sensor, LM2904
The Grove - Loudness Sensor is designed to detect the loudness of environmental sound. Based on amplifier LM2904 and a built-in microphone, it amplifies and filters the high frequency signal that received from the microphone, and outputs a positive envelop. This will make for Arduino's signal acquisition. The output value depends on the level of sound input. In order to avoid unnecessary signal disturbances, input signal will go through two times filtering inside the module. Lastly, there is a screw potentiometer that enables manual adjustments to the output gain.
Features
• Grove compatible interface
• Wide supply voltage range
• Built-in signal filtering
• Gain adjustable via screw potentiometer
