About this product

The 7Semi SHT40 Digital Humidity and Temperature Sensor Probe is designed for accurate environmental monitoring and embedded sensing applications. It provides +/-0.2 C typical temperature accuracy and +/-1.8% RH typical humidity accuracy, with digital communication through an I2C interface using a fixed 0x44 address.

The probe supports a 0–100% RH measurement range and is designed for operation from −10 C to +70 C. An integrated heater provides multiple heating levels for applications where condensation or high humidity may affect measurements. The sensor is housed in a ventilated stainless-steel probe with ventilation holes and is supplied with a 1-meter 4-wire PVC cable for convenient remote installation.

Key Features

High-Accuracy Temperature Measurement: Provides +/-0.2 C typical temperature accuracy for reliable environmental monitoring.
High-Accuracy Humidity Measurement: Delivers +/-1.8% RH typical accuracy across a 0–100% RH measurement range.
Digital I2C Interface: Provides direct digital temperature and humidity measurements for easy integration with microcontrollers, data loggers, and monitoring systems.
Fixed I2C Address: Uses a fixed 0x44 I2C address for simple and consistent communication with the host controller.
Wide Supply Voltage Range: Operates from 1.08 V to 3.6 V DC, supporting low-voltage and low-power embedded systems.
Integrated Heater: Features an internal heater with multiple heating levels to support operation in high-humidity and condensation-prone environments.
Ventilated Stainless-Steel Probe Housing: Features micro ventilation holes that allow ambient air to reach the sensing element while providing mechanical protection.
1-Meter 4-Wire PVC Cable: Provides convenient remote probe placement and straightforward I2C connection to the host system.
Low-Power Operation: Suitable for continuous environmental monitoring, portable equipment, data logging, and battery-powered applications.
Optional Breathable Protective Membrane: Available with an optional breathable membrane to help protect the sensing element from dust, water droplets, and environmental contaminants while maintaining airflow for accurate temperature and humidity measurement.

Customization: The breathable protective membrane, probe operating temperature range, and probe dimensions/length can be customized for quantity orders based on application requirements. Contact info@7semi.com for more details.
