Details of Data Frame Format: 11bits-syn bits: 00000000000b 1bit-start bit: 1b 3bits-Channel ID: Channel ID: • Channel 1 (001b) • Channel 2 (000b) • Channel 3 (010b) 11bits-temperature(Hex): • Temperature range: –500C ~ +700C • Oven +700C: 700H • Below -500C: 600H • –500C ~ +700C: Hex (temperatured + 500d) e.g. 25.50C => Hex(255d+500d)=>2F3H 7bits-humidity(Hex): • Humidity range: 0%~100% • Direct converts Dec to Hex value 3bits- miscellanies (low battery): Bit 3 is low battery status, if this bit is 1, it indicate low battery now. If this bit is 0, it indicates enough battery now. • Battery Enough: 000 • Battery Low: 100 4bits-CRC check code: It is generated by P (x)=11001b and data (3bits - Channel ID, 11bits – temperature (Hex), 7bits - humidity (Hex), 3bits – miscellanies) Total number of bit is 40 Logic "0" Logic "1" 2 ms 6 ms 6 ms 2 ms
