Integrated design for receiving and sending, one main control board is connected to 12 receiving and sending integrated waterproof probes, each probe works independently 2, waterproof probe color red, white, blue, green, black, yellow optional, other colors can be customized; 3, detection range: 13cm-450cm, the measurement can reach 150cm; 4, the detection frequency can reach 50Hz, which can detect 50 times per second; 5, support I2C / TTL serial interface, compatible with KS103 protocol; support 485 interface; 6, a total of 20 modifiable I2C / TTL / 485 addresses, ranging from 0xd0 to 0xfe (except 0xf0,0xf2,0xf4,0xf6, 8-bit address); 7, 5s Without receiving the I2C control instruction, it automatically enters the uA level sleep, and can b e awakened by the host I2C control instruction at any time; 8, using industrial grade configuration, working temperature (-30 ℃ ~ + 85 ℃); 9, Wide operating voltage range (3.0V ~ 5.5V); 10, I2C mode communication rate 50 ~ 100kbit / s; TTL / 485 serial port communication rate default 9600bps; users can modify to 115200bps, etc. ; 11, using unique adjustable filter noise reduction technology, when the power supply voltage is disturbed or noisy, it can still work normally Parameter I2C / TTL working voltage: 3.0V ~ 5.5V; or 12V ~ 24V DC power supply (12V recommended). Use 485 interface working voltage: 4.5V ~ 5.5V; or 12V ~ 24V DC power supply (12V recommended). When using 24V, please pay attention to ventilation and heat dissipation. Note: If 3.0V ~ 5.5V is connected, it is recommended to disconnect 12V ~ 24V power; if 12V ~ 24V is connected, it is recommended to disconnect 3.0V ~ 5.5V power. Instantaneous maximum current during operation: 200mA@5.0V, typical. Working current: 100mA@5.0V, typical Maximum power consumption during sleep: 500uA@5.0V, typical (do not sleep during serial mode)
