Main structure of digital temperature sensor for cold chain vehicle:
Characteristics of digital temperature sensor for cold chain vehicle:
Support "1-wire bus" interface. The field temperature is directly transmitted in the digital transmission mode of "one wire bus", which greatly improves the anti-interference performance of the system. Field temperature measurement suitable for harsh environments.
Performance of digital temperature sensor for cold chain vehicle:
1. adopt single bus special technology, not only through the serial port line, but also through other i/o port line and microcomputer interface, without other conversion circuit, output the measured temperature directly.
II. the range of temperature measurement is -55 DEG C to +125 DEG C; the accuracy is 0.5 ~+85 at the temperature range of -10 degrees C.
3. can be supplied by data line; voltage range: 3.0~5.5V.
4. negative pressure characteristics. Parasitic power source.
programmable resolution is 9~12 bits; the corresponding resolvable temperature is 0.5, 0.25, 0.125 and 0.0625, respectively.
intron 64 by ROM laser modified read-only memory.
adapting a variety of SCM or system machine.
the user can set the upper and lower temperature respectively.
each chip only supports zero power for addressing network encoding.
The stainless steel protective tube package for 6 * 30; sealing.
Application of digital temperature sensor for cold chain vehicle:
It is mainly used in temperature monitoring and monitoring in GPRS/GPS temperature monitoring system of refrigerated transport vehicle.
