ขาย US-025/A ultrasonic sensor module ราคาที่ดีที่สุด

US-025/A ultrasonic sensor module The high-performance, low-cost ultrasonic ranging module is introduced; the module adopts the high-performance ultrasonic ranging chip CS100 of Suzhou Shunyu Zhilian; the ranging is up to 6 meters, the ranging accuracy is high; the measurement consistency is good, the ranging is stable. reliable. The US-025/US-026 ultrasonic ranging module can realize non-contact ranging function of 2cm~6m, working voltage is 3V-5.5V, working current is 5.3mA, support GPIO communication mode, and work stably and reliably. US-025 has the same performance as US-026, the same size and the same principle. the difference: US-025 uses a double panel, US-026 uses a single panel; US-025 's 4Pin pin header is soldered on the front side (the probe side), US-026 is a single panel, the front side (the probe side) has no pad, and the pad is soldered on the back side (chip side). Code: // us-025 / us-026 high-precision ranging routines Unsigned int EchoPin = 2; Unsigned int TrigPin = 3; Unsigned long Time_Echo_us = 0; // Len_mm_X100 = length * 100 Unsigned long Len_mm_X100 = 0; Unsigned long Len_Integer = 0; // Unsigned int Len_Fraction = 0; Void setup () { Serial. The begin (9600); PinMode (EchoPin, INPUT); PinMode (TrigPin, the OUTPUT); } Void loop () { DigitalWrite (TrigPin, HIGH); DelayMicroseconds (50); DigitalWrite (TrigPin, LOW); Time_Echo_us = pulseIn (EchoPin, HIGH); If ((Time_Echo_us 60000) (Time_Echo_us 1)) { Len_mm_X100 = (Time_Echo_us * 34) / 2; Len_Integer = Len_mm_X100/100; Len_Fraction = Len_mm_X100%100; Serial. Print (" the Present Length is: "); Serial. Print (Len_Integer, DEC); Serial. Print (". "); If (Len_Fraction 10) Serial. Print (" 0 "); Serial. Print (Len_Fraction, DEC); Serial. Println (" mm "); } Delay (1000); }
