Description Report Item How to use this product: A control port sends a high level above 10US, and you can wait for the high level output at the receiving port. Once there is an output, you can start the timer to count, and when the port becomes low, you can read the timing The value of the device, at this time, is the time of this ranging, to calculate the distance. Such continuous periodic measurement, you can reach the value of your mobile measurement~~~ The working principle of the module: (1) Use IO to trigger the ranging and give a high level signal of at least 10us; (2) The module automatically sends 8 40khz square waves, and automatically detects whether there is a signal return; (3) There is a signal return, a high level is output through IO, and the duration of the high level is the time from the ultrasonic wave to the return. Test distance = (high level time * speed of sound (340M/S))/2; Working voltage: DC 5V *Working current: 2.2mA *Working temperature: 0~+70 degrees *Output method: GPI0 *Induction angle: less than 15 degrees *Detection distance: 2cm-400cm *Detection accuracy: 0.3cm+1% *Size: 44mm*20mm*14.8mm Weight: 7 grams US-016 Ultrasonic Ranging Module Note: US-016 is the only ultrasonic distance measuring module with analog output on the market. The output analog voltage is proportional to the distance value and can be easily connected to other systems. US-016 works stably and reliably. Overview: The US-016 ultrasonic distance measurement module can realize the non-contact distance measurement function of 2cm~3m. The power supply voltage is 5V and the working current is 3.8mA. It supports analog voltage output and is stable and reliable. This module can be set to different ranges according to different application scenarios (the maximum measuring distance is 1m and 3m respectively); when the Range pin is suspended, the range is 3m. US-016 can convert the measured distance into an analog volta
