DHT22 and Finger print sensors. R307 fingerprint module is a fingerprint sensor with a TTL UART interface for direct connections to microcontroller UART or to PC through MAX232 / USB-Serial adapter. The user can store the fingerprint data in the module and can configure it in 1:1 or 1: N mode for identifying the person. The FP module can directly interface with 3.3 or 5v Microcontroller. A level converter (like MAX232) is required for interfacing with PC serial port. DHT22 has 3 to 5V power and I/O, 2.5mA max current use during conversion (while requesting data), good for 0-100% humidity readings with 2-5% accuracy, good for -40 to 80°C temperature readings ±0.5°C accuracy, no more than 0.5 Hz sampling rate (once every 2 seconds) Price of DHT22 300 Birr Price of R307 Finger Print sensor 1100 Birr Address Megenagna Zefmesh Grandmall 3rd floor 301 0922787347/0924468599/0923522790
