Module instructions
1. The thermistor module is very sensitive to ambient temperature and is generally used to detect the temperature of the surrounding environment;
2. By adjusting the potentiometer, you can change the temperature detection threshold (that is, the control temperature value). If you need to control the ambient temperature to 50 degrees, the module will adjust its green light to the corresponding ambient temperature, and the DO will output low power. When the temperature is lower than the set temperature value, the output is high and the green light is off;
3. The DO output terminal can be directly connected with the single-chip microcomputer, and the high and low level can be detected by the single-chip microcomputer, thereby detecting the temperature change of the environment;
4. The DO output terminal can directly drive the relay module of our store, which can form a temperature control switch to control the working temperature of related equipment, and can also be connected to a fan for heat dissipation, etc.;
5. The temperature detection range of this module is 20-80 degrees Celsius;
6. This module can also be replaced with a temperature sensor with wires for the control of water temperature, water tank, etc.
7. The analog output AO of the small board can be connected to the AD module of our shop. Through AD conversion, a more accurate value of the ambient temperature can be obtained

Product Description
1. The AMG8833 infrared camera sensor is an 8x8 infrared thermal sensor array. When connected to your microcontroller (or Raspberry Pi), it will return a set of 64 individual infrared temperature readings via I2C. It's like those fancy thermal cameras, but it's compact and simple, and easy to integrate. The AMG8833 offers higher performance than the previous AMG8831. The sensor only supports I2C and has a configurable interrupt pin that can be triggered when any single pixel is above or below your set threshold.
2. It can detect humans from a distance of up to 7 meters (23) feet. It is a perfect fit for creating your own human detector or mini camera. We use this breakthrough code on or compatible (sensor communicates via I2C) or on Python's Raspberry Pi. On the Pi, thanks to the image processing help of the SciPy python library, we can insert an 8x8 grid and get some very good results!

Size:130 x 84 x 52mm / 5.11 x 3.3 x 2.04"
Instruction:
Voltage Adjustment:
Power
on module while not connect to load, then adjust "V-ADJ" potentiometer
clockwise to increase, counterclockwise to decrease. Due to large output
capacitance capacity, response will be slow when adjust high voltage to
low voltage.
Current Adjustment:
Adjust "CC A-ADJ" potentiometer
counterclockwise about 30 circles to minimize the output current before
connecting to load. Then adjust "CC A-ADJ" clockwise to the current
value you need.If you use the module for battery charging, connect to
output after battery is fully discharged. Because if the more energy is
left in battery, the less charging current will be.
Low Input Voltage Protection Adjustment:
If
we set a low input voltage protection for a 12V battery, connect input
to a 10V voltage, then adjust RV1(clockwise to increase,
counterclockwise to decrease) till UVLO light up. Now the protection
voltage is 10V, that is to say, when battery voltage drops to 10V,
module won't step up voltage and the output voltage will be same as
input voltage.
Note:
1. Output wiring can not be reversed or short circuit.
2,
If the module is connected to inductive load, the minimum input voltage
should be higher(e.g. 24V) and maximum output power should be
lower(e.g. 500W).
3, If a storage battery, switch power supply, solar
panel or electric generator is used as input power source, the low
voltage protection value should be adjusted lower, otherwise it might
cause damage.
