Photodiode + Thermistor + Sound Detection Sensor Kit for Arduino

Photodiode Sensor Module:
Feature:
1. The brightness of surrounding environment and the light intensity can be detected (compare with the photoresistor, directivity is relatively good, can perceive the fixed direction of the light source)
2. Sensitivity adjustable the blue digital potentiometer adjustment (Figure)
3. Operating voltage 3.3V -5V
4. Digital switching outputs (0 and 1)
5. With fixed bolt hole for easy installation
6.
Small board PCB size: 3.2 cm * 1.4 cm

Instruction:

1. Photodiode module which is the most sensitive module to the ambient light, used to detect the brightness of the ambient light intensity, photoresistor sensor module Universal In most cases, the difference between the two is that photodiode module can sense the fixed the direction of the light source directly.

2. Module in the light conditions or the light intensity of less than a set threshold, DO port outputs a high level, when the external environment when the light intensity exceeds the set threshold value, the module D0 output is low.

3. The small board digital output D0 can be connected directly with the microcontroller microcontroller to detect high and low to detect environmental light intensity change

4. Small board digital output DO OUR relay module can directly drive, which can be composed photoelectric switch

Digital Thermal Sensor:
Module Features:

1. Using the NTC thermistor sensor, good sensitivity

2. The comparator output signal clean waveform is good, driving ability, than 15mA.

3. Adjust the temperature distribution bit detection threshold

4. Working voltage 3.3V -5V

5.
The output format: Digital switching output (0 and 1)

6. With bolt holes for easy installation
7.
A small board PCB size: 3.2 cm x 1.4 cm

8. Using a wide voltage LM393 comparator

Module for use:

1. The thermal resistance of the module is very sensitive to the ambient temperature, generally used to detect the ambient temperature;

2. Through the adjustment of the potentiomete, can change the temperature detection threshold (ie, temperature control value), if necessary to control the ambient temperature is 50 degrees, the module in the corresponding ambient temperature to which the green light, DO output is HIGH level falls below the set temperature value, the output is high, the green light does not shine;
3. DO output can be directly connected with the microcontroller through the microcontroller to detect high and low, thereby detecting the ambient temperature changes;
4. DO OUR outputs can directly drive the relay module, which can be composed of a thermostat to control the operating temperature of related equipment can also be connected to the fan used to heat and other

5. The detection range of the module's temperature 20-80? C;

6. This module can also be replaced with a wire temperature sensor for water temperature, water tank controlled.
