1-WIRE TEMPERATURE AND HUMIDITY SENSOR
Application
1. General information
The RFID reader 1 W-H3-03 M12 reads identifi cation data wireless of passive transponders (cards, tags,etc.) compatible with UNIQUE standard.
Green – power supply (-)
Brown – power supply (+)
White – 1-Wire
The reader should be connected according to the scheme:
2. DS1990A emulation
After reading the card, the collected data is sent via the 1 -Wire interface, emulating MAXIM’s DS1990AID. The first byte is Family Code 0x01, the next 6 bytes to the UID code of the read card are sent from the least significant UID bytes. If the UID is shorter than 6 bytes, the most significant bytes are padded with zeros. The last byte is the CRC checksum of the previous 7 bytes. Each byte sent is sent starting from the least significant bit of the LSB.
To read the UID of the token, bring the token closer to the RFID reader. Token UID readings are performed cyclically every 250 ms. After correct reading of the identifier, the DS1990A system from Maxim (Dallas) is emulated through the 1-Wire interface.
