Abstract
The present invention discloses an electronic circuit for acousto-optoelectronic angle indication and a level gauge thereof. The electronic circuit for acousto-optoelectronic angle indication comprises a main control circuit (a), a power circuit (b), a key circuit (c), a sensor module circuit (d), an LED indicator module circuit (e), a buzzer module circuit (f) and a data storage module (g). The control circuit (a) comprises a microcontroller (U2), a capacitor (C2), a capacitor (C3), a capacitor (C4), a capacitor (C5), a capacitor (C6), a capacitor (C8), an electrolytic capacitor (E1), a resistor (R11), a resistor (R12) and a resistor (R20). The invention realizes an acousto-optoelectronically indicated design circuit device with high precision, so that the current angular value state can be accurately displayed through acoustic and photoelectric changes by simply placing a measuring device on a test plane.
