# IoT with Raspberry Pi: Sensors, MQTT, and Home Automation
> Practical IoT and hardware guidance for makers and engineers.
## Overview
IoT and hardware projects connect the physical and digital worlds for automation and insight.
## Key Topics
- Sensor integration
- Wireless protocols (MQTT, Zigbee, BLE)
- Edge vs. cloud processing
- Prototyping and iteration
## Example
```cpp
// Arduino: read temperature sensor
int sensorPin = A0;
void setup() { Serial.begin(9600); }
void loop() {
int value = analogRead(sensorPin);
float voltage = value * (5.0 / 1023.0);
Serial.println(voltage);
delay(1000);
}
```
