Design with ENS 160 Sensor in Cirkit DesignerThe ENS160 Sensor by Adafruit is a high-performance MOX (Metal Oxide) gas sensor designed to detect a wide range of gases, including volatile organic compounds (VOCs) and other air quality indicators. This sensor is equipped with advanced algorithms to provide accurate air quality measurements, making it ideal for applications such as environmental monitoring, HVAC systems, smart home devices, and indoor air quality management.
The ENS160 is particularly well-suited for detecting harmful gases and monitoring air quality in real-time, enabling users to maintain healthier environments. Its compact design and I²C/SPI communication interfaces make it easy to integrate into various projects and systems.
This circuit is a sensor and motor control system powered by a 9V battery and regulated by a buck converter. It includes multiple sensors (SEN0245, SEN0427, I2C BMI160) connected via I2C to an ESP32 microcontroller, which also controls two N20 motors with encoders through an MX1508 DC motor driver.

#include <Adafruit_ENS160.h>
// Create an instance of the ENS160 sensor
Adafruit_ENS160 ens160;
void setup() {
Serial.begin(115200); // Initialize serial communication for debugging
while (!Serial) delay(10); // Wait for Serial to initialize
Serial.println("Adafruit ENS160 Test");
// Initialize I²C communication and the ENS160 sensor
if (!ens160.begin()) {
Serial.println("Failed to find ENS160 sensor! Check connections.");
while (1) delay(10); // Halt if sensor is not detected
}
Serial.println("ENS160 sensor initialized successfully!");
}
void loop() {
// Read air quality data from the sensor
ens160.readData();
// Print air quality index (AQI) to the Serial Monitor
Serial.print("Air Quality Index (AQI): ");
Serial.println(ens160.getAQI());
// Print equivalent CO2 (eCO2) levels
Serial.print("Equivalent CO2 (eCO2): ");
Serial.println(ens160.getECO2());
// Print total VOCs (TVOC) levels
Serial.print("Total VOCs (TVOC): ");
Serial.println(ens160.getTVOC());
delay(1000); // Wait 1 second before the next reading
}

Q: Can the ENS160 detect specific gases?
A: The ENS160 is optimized for detecting VOCs and providing air quality indices. It does not provide specific gas concentrations but offers equivalent CO2 (eCO2) and total VOC (TVOC) levels.
Q: Can I use the ENS160 with a 5V microcontroller?
A: Yes, the ENS160 breakout board includes level-shifting circuitry, making it compatible with both 3.3V and 5V systems.
Q: How often should I calibrate the sensor?
A: The ENS160 is factory-calibrated and does not require user calibration. However, ensure proper placement and avoid contaminants for consistent performance.
Q: What is the typical response time of the sensor?
A: The ENS160 has a fast response time, typically within a few seconds, depending on the gas concentration and environmental conditions.
