Sensors and Actuators
These components expand your ESP32 C3 Super Mini capabilities for various projects:
Buy Note: Many DS18B20 sensors available in the market are unreliable. We strongly recommend buying the sensor from the DIYables brand using the link provided above. We tested it, and it worked reliably.
Buy Note: For controlling multiple servo motors, use the PCA9685 16 Channel PWM Servo Driver Module to save MCU pins and simplify wiring.
Component categories explained:
- Input Devices: Buttons, keypads, sensors detect user actions and environmental data
- Output Devices: LEDs, buzzers, LCDs provide visual and audio feedback
- Motion Components: Servo motors and stepper motors create physical movement
- Control Components: Relays and motor shields switch high-power devices safely
- Security Components: Door sensors, electromagnetic locks, motion sensors for smart home projects
Choosing between alternatives:
- Button options: Breadboard-mount for prototyping, panel-mount for permanent installations
- Keypad options: 3x4 for basic input, 4x4 for more options (like calculator layout)
- Temperature sensor: WITH adapter is easier for beginners, WITHOUT requires additional wiring
- Buzzer options: Active buzzers are simpler (just turn on/off), passive buzzers can play melodies
- Potentiometer options: Standard potentiometer for basic projects, module with knob for polished look
Popular ESP32 C3 Super Mini project combinations:
- Home automation: Motion sensor + relay + light sensor for smart lighting
- Security system: Door sensor + electromagnetic lock + keypad for access control
