BME280 vs SHT30 — Environmental Sensor Comparison
Choosing between BME280 and SHT30 is one of the most common sensor decisions in IoT hardware design.
BME280 Advantages
- Adds barometric pressure — 3-in-1 environmental sensing
- Lower power sleep modes — Better for battery devices
- Wider ecosystem — More Arduino/Pi libraries and examples
SHT30 Advantages
- Higher accuracy — ±2% RH vs ±3% for BME280
- Faster response time — Better for HVAC control loops
- Simpler I2C protocol — Easier firmware integration
Price Comparison (1K qty)
| Part | Unit Price | In Stock | |------|-----------|----------| | BME280 | ~$2.35 | Yes | | SHT30-DIS-B | ~$2.05 | Yes |
Recommendation
Use BME280 when you need pressure data or lowest BOM cost. Use SHT30 when humidity accuracy is critical. Both are in stock at Wizard — request a quote for your quantity.
