wireless temperature sensor | Wireless temperature of SONBEST

Dimensions: 120 (L) * 100 (W) * 50 (H) mm

Installation: Wall

Supply Voltage: 5 ~ 12v

Sensor: The Swiss precision digital sensor producing SHT10

2, Function

1, the temperature real-time acquisition and display

Temperature data collected once per second transmitter, the transmitter uses bright LED digital tube display real-time 2-way collected data on temperature and humidity, precision 1 decimal point,

2, operation, and communications instructions

Instrumentation with green LED indicates the current system operating state, when the devices work properly when running lights flash once per second, when the light goes out or the light is the sensor fault.

Direct communication with the red LED instrument status to the host computer when the transmitter receives a request sent over the data command, the flash, when not receiving data or communications line failure will go out

3, fault indication

When the transmitter does not receive the temperature sensor 10 DS18B20 data, then that sensor failure, the corresponding digital control, when the sensor fault was removed, then returned to normal temperature display.

3, RS485 communication

Transmitter PC using RS485 bus and data transmission, communications chip using TI's 75LBC184 lightning communications chips, the bus up to 64 nodes, the transmitter with DC / DC dual power supply and opto-isolation, a strong guarantee communication reliability and stability.
