Description

The 7Semi ENS210 breakout module integrates a factory-calibrated digital sensor IC for simultaneous temperature and humidity measurement. It employs a capacitive sensing element for humidity and a band-gap sensor for temperature, delivering stable, pre-processed digital readings via the I2C bus, eliminating the need for external signal conditioning.

Designed for low-voltage embedded systems, it operates from 1.71V to 3.6V, making it compatible with both 3.3V and 5V logic (with appropriate level-shifting). Its minimal power draw and standby mode make it ideal for continuous environmental monitoring in IoT networks, HVAC control systems, and portable data loggers where energy efficiency is critical.

Key Features

High-Accuracy Digital Sensor: Delivers factory-calibrated temperature (±0.15°C) and humidity (±2.0% RH) data with excellent long-term stability.
Ultra-Low Power Profile: Consumes only 6.6 µA at a 1Hz measurement rate, with a standby current as low as 0.04 µA for extended battery life.
Wide Operating Ranges: Functions reliably across a full humidity span (0-100% RH) and an extended temperature range from -40°C to +100°C.
Robust Digital Interface: Standard I2C communication supports both standard (100 kbit/s) and fast (400 kbit/s) modes for flexible system integration.
Compact Breakout Design: Small-form-factor PCB (19x11x6 mm) includes all necessary pull-up resistors and decoupling for reliable operation.
Broad Compatibility: Ready-to-use with popular development platforms like Arduino, ESP8266/32, Raspberry Pi, and STM32 via simple I2C libraries.

Applications

HVAC and building automation systems for precise climate control and energy management.
IoT environmental monitoring nodes in smart agriculture, greenhouses, and weather stations.
Portable data loggers and wearable devices requiring low-power, high-accuracy sensing.
Industrial process monitoring and equipment condition monitoring in harsh environments.
Consumer electronics and smart home devices for indoor air quality and comfort sensing.

Frequently Asked Questions

What is the operating voltage range for the ENS210 breakout module?

The ENS210 operates from 1.71V to 3.60V DC. This makes it natively compatible with 3.3V logic microcontrollers. For use with 5V systems like Arduino Uno, a logic level converter is required on the I2C lines (SDA, SCL) to prevent damage to the sensor.

How do I connect and read data from the ENS210 using an Arduino?

Connect the breakout's VCC to 3.3V, GND to GND, SDA to the Arduino's SDA pin (A4 on Uno), and SCL to SCL (A5 on Uno). Use a 3.3V-compatible logic level shifter if your Arduino operates at 5V. Data is retrieved via the I2C bus using dedicated libraries available from 7Semi or community sources.

What is the power consumption during continuous measurement?

The sensor is designed for ultra-low power applications. At a 1Hz sampling rate and 1.8V supply, the active current is typically 6.6 µA. The standby current can be as low as 0.04 µA, making it highly suitable for battery-powered IoT nodes and wireless sensor networks.

Is the sensor calibrated, and what is its accuracy?

Yes, the ENS210 is factory calibrated. It provides a high temperature accuracy of ±0.15°C and a typical humidity accuracy of ±2.0% RH across its full measurement range. This calibrated digital output ensures reliable, ready-to-use data without requiring user calibration.
