DHT11 Digital Temperature & Humidity Sensor Module (and DHT22 family) – Low-cost digital humidity/temperature sensors with single-wire interface.

BME280/I2C Temperature‐Humidity‐Pressure Sensor Module (or BME family) – Multi-parameter I2C sensors measuring temperature, humidity, pressure; higher accuracy.

Thermistors & Analog Temperature Sensors – Simple analog sensors (e.g., LM35, NTC thermistors) useful for basic temperature monitoring and educational projects.

IR (Infrared) Temperature Sensors – Non-contact sensors measuring surface temperature via infrared radiation; ideal for target surfaces and moving objects.

Comparison of Sensor Types: Accuracy, Range & Ease of Use

Sensor Type	Typical Accuracy & Range	Ease of Use	Notes
DHT (e.g., DHT11 / DHT22)	DHT11: –20 °C to 60 °C, ±2 °C DHT22: –40 °C to 80 °C, ±0.5 °C	Very easy – simple digital line	Good for basic projects
BME280 / Multi-parameter	–40 °C to 85 °C, ±1 °C (temp); also measures pressure & humidity	Moderate – I2C, library needed	Higher precision, more features
Thermistor / LM35	e.g., –55 °C to 150 °C; accuracy depends on calibration	Easy – analog reading	Requires analog pin and calibration
IR Temperature Sensor	Surface readings: –70 °C to 380 °C; accuracy ~±0.5 °C	Moderate – needs line-of-sight	Good for non-contact measuring

Applications: Weather Stations, IoT, Smart Home & HVAC Monitoring

Build a weather station: use DHT/BME sensors to monitor temperature, humidity and pressure, send data to the cloud.

IoT environment monitoring: Use Raspberry Pi or ESP32 + sensor modules to log indoor/outdoor temperature remotely.

Integrate into smart home: Read room temperature to control HVAC, fans, or ventilation automatically.

Robotics and automation: Thermal monitoring of motors or µC boards; use IR sensors to detect hotspots or surface temperatures.

HVAC and industrial monitoring: Thermistors or IR sensors used to check duct temperatures, fluid flows, or equipment housing.

Installation & Calibration Tips

Mount sensors away from heat sources or air vents to avoid skewed readings.

For analog sensors: calibrate with known temperature points (e.g., ice bath, boiling water) and map readings accordingly.

For DHT/BME sensors: allow 30–60 seconds of warm-up after power-on for stable readings.

Use shielded or short wiring if sensors are far from microcontroller to avoid noise, especially in industrial/IoT setups.

For IR sensors: ensure object surface is within sensor field-of-view; avoid reflective surfaces that may distort readings.

When logging data over time, record and compare readings at known stable temperatures to identify offsets and apply software corrections.
