Store Catagory Store Catagory Red DS18B20 6-15V Digital Display Thermometer Module Photosensitive Control Product Introduction:

1.Adopt DS18B20 digital temperature sensor to achieve high precision temperature

measurement

2.Display adopts 0.56 inch 4-bit +0.36 inch 1-bit highlight digital tube

3.Measurement Display Range:-50~+125 celsius

4.The thermometer defaults to use 6-15V DC power

5.Operating Current:60mA

6.Photosensitive control function,and the display brightness will change according to ambient

brightness

7.Precision 0.1 celsius temperature control output function,and users can set temperature

control upper limit and lower limit

8.Output temperature control signal voltage is lower 0.5V than power supply voltage,and it

has 300mA driving capacity;it can directly drive small relay etc

Features:

1.Intelligent photosensitive control

2.0.1 celsius precision temperature control signal output function

3.Temperature control signal reverse phase output function,and it can be applied to

temperature alarm,refrigerating,heating etc

Parameter Settings:

1.In normal operating state,long press SET key,please loosen the SET key when it displays th

on the screen;then enter into temperature control parameter setting state,and it will display th

value (temperature control upper value) on the screen. +,- key is for adjusting the value,and

the range is -50.0~125.0;short press the key is for stepping adjustment,and long press +,- key

is for fast adjustment

2.Press the SET key,then it will display tL on the screen;if loosen the key,then it will display tL

value (temperature control lower value).+,- key is for adjusting the value,and the range is

-50.0~125.0;short press the key is for stepping adjustment,and long press +,- key is for fast

adjustment

3.Press the SET key,then it will display AL on the screen;if loosen the key,then it will enter into

temperature control output mode setting;the screen will display AL0 or AL1,pressing +,- key

can modify the value 0 or 1.

AL0 Definition:measured temperature >= temperature setting upper value,or measured

temperaure <= temperature setting lower value,and the temperature control output port will

output voltage

AL1 Definition:temperature setting lower value < measured temperature < temperature

setting upper value,and temperature control port outputs voltage

4.Press the SET key,it will display SAV on the screen;parameters will be saved and come

back to normal operating state

5.Exceptional Circumstances:if the temperature setting lower value >= temperature setting

upper value;then when temperature control output mode is AL0,the temperature control output

port will output voltage;when the temperature control output mode is AL1,then the

temperature control output port has no voltage continuously

Display Screen Brightness Setting:

If users want to change the brightness on the screen,or let the brightness change according to

ambient brightness,please set as below:

1.The thermometer should be placed in normal operating position,and let the photosensitive

resistor receive ambient light normally;there cannot be any barriers or reflection of light

2.The Display Brightness Settings In Maximum Ambient Temperature

When ambient light reaches to the strongest,if long press the SET key,then it will display bh

on the screen;if loosen the SET key,it will enter into brightness upper value setting state,and it

will display bh value on the screen;pressing +,- key can adjust reasonable brightness (the

adjustment range is 1-20,and the brightness will be changed at the same time when adjust the

value);press the SET key,the screen will display SAV;and the setting parameters will be

saved and come back to normal operating state

3.The Display Brightness Settings In Minimum Ambient Temperature

When ambient light reaches to the weakest,if long press the SET key,then it will display bL

on the screen;if loosen the SET key,it will enter into brightness lower value setting state,and it

will display bL value on the screen;pressing +,- key can adjust reasonable brightness (the

adjustment range is 1-20,and the brightness will be changed at the same time when adjust the

value);press the SET key,the screen will display SAV;and the setting parameters will be

saved and come back to normal operating state

Notice:if there is no +,- operations on the parameter when setting,then it is invalid setting

and the data won't be saved

5.After finish setting,when the ambient brightness is changing from the weakest and the

strongest,then the brightness on the display screen will be changed in the range of lower

value and upper value

6.When the brightness upper value is equal to lowe value,then the brightness of the screen is

fixed and won't change

Connection:

1.Temperature control output wire (orange+/blue-) length 20cm;power wire (red+/black-)

length 20cm;sensor wire (white) length 30cm

2.Note:If users don't want to use temperature control function,please do not plug in the

temperature control output wire in case of short circuit
