DC Temperature Sensor Module (3.3V-12V NTC-10K ~10% Thermistor)
$42.15
$72.92
1. Description: The temperature sensor test temperature,and the voltage comparison to detect the temperature. When the temperature is greater than the set point, the DO outputs are low. 2. Feature: 1>. /- 1% waterproof thermistor probe, and the line length is 50cm 2>. The on-board processor has high accuracy, fast response and good quality 3>. The board adjustable potentiometer has high sensitivity. 3. Parameter: NO. Parameter Value 1 size 30*15*8 mm 2 Voltage 3.3-12VDC 3 Current Operating < 20ma; output <30ma 4 Interface - DO(Digital quantity) AO(Analog quantity) 5 Purpose Test temperature 4. Instructions 1>. " " connected to the positive pole "-" connected to the negative pole. Then the power is connected, "P" the power indicator lighting up. The module work properly. 2>. The blue potentiometer is adjusted clockwise / counterclockwise, respectively, which can increase / decrease the sensitivity of the probe. 3>. The potentiometer is adjusted clockwise to "S". When the output indicator is on, it indicates that the range of adjustment has exceeded the test threshold; while adjusting the counter to the limit when you cannot adjust it. Adjustment can not exceed the threshold, otherwise it can not be used properly. Voltage regulation is only used for the "DO" port and is not associated with the "AO" output. 4>. The "AO" output can be detected directly through the AD port of the MCU.
