Commonly used digital DS18B20 temperature sensor is a temperature sensor through the stainless steel tube package, so as to achieve the waterproofing, insulation, protection, heat conduction effect, and used for various measurement in harsh environment.
DS18B20's main parameters of elements:
Single line interface unique,DS18B20 only one line can be realized in microprocessor and connected with the microprocessor when DS18B20 two-way communication.
The temperature range of -55C ~+125C, in-10~+85℃ accuracy is ±0.5C.
DS18B20 support multi-point network function, multiple DS18B20 can be connected in parallel in three online only, achieve network multi-point temperature measurement. If the amount is too much, it will make the power supply voltage is too low, resulting in the instability of signal transmission.
The working power supply: 3.0~5.5V/DC(data line parasitic power)
DS18B20 does not need any external components when using, all sensor and conversion circuit are integrated into the shape of a transistor in integrated circuit.
The programmable resolution 9~12A, the corresponding resolvable temperature respectively 0.5C, 0.25C, 0.125C and 0.0625C, can achieve high precision temperature measurement.
The pressure features: power supply polarity reverse connection, the chip will not burn with fever.
When ordering, please inform the following parameters:
1 Installation dimension of 1 element DS18B20: common 6x30mm, 6x50mm (other size customization)
2 wire output? (usually 2 wire /3 wire choose one)
3 wire requirements? (high temperature / wear / corrosion / ex / water / other)
4 The lead line length? (common 1M/2M/3M/4M/5M standard)
5 Tail compensating conductor? (tin /U terminal / metal wire / terminal)
6 other special requirements, special occasions custom please explain in detail
