Taidacent Waterproof Ultra-Precision Ultrasonic Sensor Presence and Detection Parking Occupancy Sensor Vehicle Presence Detector Ultrasonic Range Detector in Outdoor (UART Serial Port)
Product description and advantages Ultrasonic distance sensor module of TD-A02-V2.0 is a high performance , and designed by using a enclosed type and splinched waterproof probe . which has a certain dust waterproof level, suitable for the wet and poor measurement occasions. smaller blind zone distance of 3cm apply to different detection conditions,simple operation and they are the commercial grade modulewith high-performance and high reliability.Ultrasonic distance sensor module of TD-A02-V2.0 is a high performance , and designed by using a enclosed type and splinched waterproof probe . which has a certain dust waterproof level, suitable for the wet and poor measurement occasions. smaller blind zone distance of 3cm apply to different detection conditions,simple operation and they are the commercial grade modulewith high-performance and high reliability. Advantages Smaller blind Strong anti-interference; Data output, stable and reliable; Minimize power consumption Fast response time; Strong antistatic Wide working temperature; High measurement accuracy; Parameter Blind zone distance 3cm blind Power supply 3.3~5V Average working current ≤5mA Peak-peak value current ≤40mA Flat object range 3~450cm Reference angle ≈60° Room temperature measurement ±(1+S0.5%)cm Application Level distance measurement Parking management system Robot obstacle avoidance , automatic control; Detect the objects close to and the existence of external objects; Output pin definition 1, VCC, Power input lead 2, GND, Power ground lead 3, RX, Processing value and real-time value output selection lead(1) 4, TX, UART output lead(1) Remark:(1)The function of lead and pin corresponds to the output mode of product model one by one, and cannot coexist with other output modes. Communication instructions of UART When the trigger input pin - “RX” is suspended or input a high level, the module outputs according to the processing value, the data is more stable ,and the response time is 100-500ms;when the input a low level trigger,it is output according to the real-time value,and the response time is 100ms. UART:TTL electrical level; Data bit:8; Stop bit: 1; Parity check:Not; Baud rate: 9600bps UART output format Frame data: Frame header, Instructions: Fixed to 0XFF, 1 byte; Frame data: Data_H, Instructions: High 8 bits of distance data, 1 byte; Frame data: Data_L, Instructions: Low 8 bits of distance data, 1 byte; Frame data: SUM, Instructions: Checksum of communication, 1 byte Example of UART output Frame header:0XFF ; Data_H:0X07 ; Data_L:0XA1 ; SUM:0XA7; Remark:The checksum retains the low 8 bits of accumulative value only; SUM =(Frame heade+ Data_H+ Data_L)&0x00FF =(0XFF + 0X07 + 0XA1)&0x00FF =0XA7; Distance value= Data_H256+ Data_L=0X07A1;Converted to a decimal is 1953; Means the current measured distance value is 1953mm; The effective detection range The tested object is the white cylindrical tube, material is PVC, height is 1000mm, diameter is 75mm.The tested object is the corrugated case, perpendicular to 0°axle wire, length is 60cm, width is 50cm.
