Product features:
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.
Product performance:
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.
Platinum resistance temperature sensor:
High precision import of Japan / Germany platinum resistor element chip;
