Supplier's note

1. Three Technical Breakthroughs:

   • Low Power Consumption: The SHT25’s 1.0 µA sleep mode reduces energy use by 60% vs. competitors, ideal for battery-powered IoT devices.
   • ESD Protection: The Pro model withstands ±8 kV contact discharge, enabling safe use in industrial settings with electrical noise.
   • Miniature Size: At 2.5 x 2.5 x 0.9 mm, the SHT20 saves space in compact devices like wearable environmental monitors.

2. Optimal Version Selection:

   • Industrial Automation (Factories): Choose the SHT25 for its ±0.3°C accuracy and 2 s response time to monitor real-time process conditions in HVAC systems.
   • Consumer Electronics (Smart Home): The SHT20’s cost-effective design suits low-power smart thermostats.
   • Outdoor Monitoring (Weather Stations): Pair the SHT21 with an IP67 enclosure to leverage its ±1.5% RH accuracy in fluctuating outdoor environments.

With the SHT25’s triple-industry-standard ESD protection, you can ensure reliable operation in factories with high electromagnetic interference. When combined with its ±0.3°C precision, this creates a robust solution for temperature-critical processes like semiconductor manufacturing.
