Attāluma un šķēršļu sensori

ElektronikaSensori – Attāluma un škēršļu sensori

HC-SR04 Ultraskaņas attāluma sensors
Ultrasonic distance measuring transducer sensor module.
Spriegums: 5V(DC).
Statiskais strāvas stiprums: mazāk kā 2mA.
Kontakti: 1.VCC 5V, 2.trig(T) ieeja, 3.echo(R) izeja, 4.GND.
Ieejas (trigger) signāls: vismaz 10us (high) TTL impulse
Izejas (echo) signāls: Electric frequency output TTL PWL signal – high 5V, low 0V.
!! Neslēdziet Echo(5V) izeju tieši pie Raspberry Pi 3.3V pin, vajadzīga sprieguma samazināšana (voltage divider)!
Sensora leņķis: līdz 15 grādiem.
Mērīšanas attālums: 2cm-450cm, precizitāte līdz 0.3cm.
Kad ieeja (trigger) saņem high impulsu, modulis automātiski sūta astoņus 40kHz kvadrātviļņus un, kad uztver tos, dod izejā (echo) high. Attālumu nosaka pēc ultraskaņas pavadītā ilguma ceļā.
Attālums = (Laiks * Skaņas ātrums(340m/s) / 2
Modulim ir jābūt savienotam pirms pieslēgšanas strāvai, lai nerastos kļūdas.

KY-032 Šķēršļu izvairīšanās infrasarkanā sensora modulis
IR Obstacle avoidance sensor module
Spriegums: DC 3.3V-5V
Strāvas stiprums: ≥ 20mA
Darba temperatūra: -10 ℃ – +50 ℃
Mērīšanas attālums: 2-40cm
IO Interface: 4-wire interfaces (- / + / S / EN)
Output signal: TTL level (low level there is an obstacle, no obstacle high)
Adjustment: adjust multi-turn resistance

Infrared obstacle avoidance sensor is designed for the design of a wheeled robot obstacle avoidance sensor distance adjustable. This ambient light sensor Adaptable, high precision, having a pair of infrared transmitter and receiver, transmitter tubes emit a certain frequency of infrared, When detecting the direction of an obstacle (reflector), the infrared receiver tube receiver is reflected back, when the indicator is lit, Through the circuit, the signal output interface output digital signal that can be detected by means of potentiometer knob to adjust the distance, the effective distance From 2 ~ 40cm, working voltage of 3.3V-5V, operating oltage range as broad, relatively large fluctuations in the power supply voltage of the situation Stable condition and still work for a variety of microcontrollers, Arduino controller, BS2 controller, attached to the robot that
Can sense changes in their surroundings.
