T117 digital signal temperature sensor


The DS18B20, a digital temperature sensor imported from the United States, was sealed with high thermal conductivity, which ensured the high sensitivity of temperature sensor and the minimum temperature delay.

The temperature sensor support "1-wire bus" interface (1 - Wire), measuring temperature range for - 55 ° C to + 125 ° C, in - 10 ~ + 85 ° C range, accuracy of + / - 0.5 ° C.

The field temperature is transmitted directly in the digital way of "1-wire bus", which greatly improves the anti-interference of the system. Suitable for the temperature measurement of the environment.

The DS18B20 digital temperature sensor has a unique number, and the temperature acquisition device is used to identify the corresponding temperature sensor.

The length of the sensor's lead can be customized according to the user's needs.


The advanced single-bus data communication, unique single wire interface requires only one port pin to communicate

Power supply voltage: DC 3.0 V ~ 5.5 V.

Low test temperature range for - 55 ° C to + 125 ° C (67 ° F ~ + 257 ° F).

Low in - 10 ~ + 85 ℃ range precision can reach 0.5 degrees Celsius soil;

The maximum working period of the 12-bit resolution is 750 milliseconds.

Each device has a unique 64-bit serial number stored in internal storage;

Internal EEPROM, temperature limiting alarm function;

A variety of packaging forms to adapt to different hardware systems;

It can realize multi-point distributed temperature measurement application.


Low probe adopt new imported DS18B20 temperature sensor chip, chip each pin are separated with heat shrinkable tube, prevent short circuit, high quality stainless steel tube encapsulation, internal sealing glue, waterproof and moistureproof prevent rust.Stainless steel head lead 1 meter, steel pipe 6* 50mm.

Each probe is strictly tested

A unique single bus interface without external components.

The temperature sensor adopts a stainless steel sheath with a layer of high thermal insulating silicone grease and a layer of insulating sealant, which makes the sensor more sensitive to the change of temperature.

The length of the sensor cable is 1 meter, and the installation connector is equipped with the matching of the GPRS type and the full range car machine (please specify the length of the extension cord when ordering).


1. When installing, please install the sensor as far as possible in the temperature area of the object or environment. When installed in the insulated car, the sensor can be installed in the height of one half of the car's height, so that the temperature of the measurement will not be changed due to the operation of the air conditioning unit.

2. When installing, install the sensor as far as possible to avoid the collision of the goods and avoid damage to the sensor during the collision.

3. The position of the sensor installation should avoid the position of water accumulation and narrow gap in space. The temperature of such position can be measured with the actual temperature and error and delay.

4. If there are other types of temperature recording devices on the vehicle, please install them in the same location with the probe of the equipment so that the consistency of recording temperature of different equipment can be improved.

5. The sensor walking line should avoid the high temperature area of the vehicle (such as engine, water tank).The wiring should be in line with the original car wire, and the wire should be fastened with the tie strap.

6. Walk the line as far as possible to avoid the dead Angle, avoid easy to squeeze, cut off the moving parts of the vehicle, avoid the failure of the line breaking, grinding short circuit.
