Avoid delay(): Use millis() for non-blocking timing so multiple sensors can operate independently.

Stagger sensor reads: Schedule sensors like DHT or ultrasonic at different intervals to avoid overlapping.

Use interrupts carefully: Only for simple, fast sensors (like motion detection), and keep ISR code minimal.

Manage I2C devices: Don’t read multiple I2C sensors simultaneously; use well-maintained libraries.

Minimize Serial.print(): It slows down loops—buffer or throttle logging.

Profile with micros(): Measure execution time to catch bottlenecks.

For complex setups, consider a simple state machine or use TaskScheduler.

Let me know which sensors you're using—I can suggest specific timing strategies.
