PRODUCT DETAILS
 
Temperature detection, temperature control sensor, ambient temperature sensor 
Module Features: 
1, NTC thermistor sensor, good sensitivity
2, the comparator output signals clean, good waveform, driving ability, than 15mA.
3, distribution position to regulate the temperature detection threshold
4, the working voltage of 3.3V-5V
5, the output form: DO digital switching output?0 and 1?And AO analog voltage output
6, a fixed bolt hole for easy installation
7, small PCB board size: 3.2cm x 1.4cm
8, using a wide voltage comparator LM393
 
วิธีการใช้งานหัววัดอุณหภูมิ สำหรับวัดอุณหภูมิห้อง: 
1, the thermistor module ambient temperature is very sensitive, generally used to detect the ambient temperature;
2, through the potentiometer adjustment, you can change the temperature detection threshold?That temperature control?Such as the need to control the ambient temperature of 50 degrees, the module in the corresponding ambient temperature to which the green light, DO output is low, the temperature falls below the set value, the output is high, the green light does not shine;
3, DO output can be directly connected to the microcontroller through the microcontroller to detect high and low, thereby detecting temperature changes in the environment;
4, DO output of the relay module can directly drive the shop, which can be composed of a thermostat switch, temperature control related equipment can also be connected to the cooling fan and so on;
5, the temperature detection range of this module is 20 to 80 degrees Celsius;
6, the temperature sensor module can also be replaced with a line for controlling the water temperature, water tanks, etc.
 
7, small plates AO analog output modules can be connected and the shop AD by AD conversion, the more accurate value can be obtained ambient temperature
 
 
Module Interfaces 4-wire
1 VCC 3.3V-5V external
2 GND External GND
3 DO small board digital output interface switch?0 and 1?
4 AO small plates analog output interface

Exchange or return policy



Every item comes with a 30-day warranty. However, there are certain conditions that apply:

  1. The customer should not be responsible for any self-inflicted damage, such as incorrect power connections (for example, supplying 5V instead of the required 3.3V for a sensor).

  2. The product must be in perfect condition, without any breakage or damage caused by electricity (e.g., short circuits leading to electrical fires).

  3. The store does not accept product exchanges due to customer misunderstandings, such as purchasing the wrong size for their project or buying something without eventually using it. Customers can inquire about the product details and ensure compatibility before making a purchase by contacting us through our Line account @modulemore during business hours. Please note that there may be delays in response between 12:00 PM and 2:00 PM.

Return Policy: To initiate a product return, customers must provide the original receipt or a copy for quick verification. Returns can be sent to our store address by following these guidelines:
