Description and Introduction

Dual Element Detector Here is the factual information about the **HEIMANN LHI778** manufacturer, specifications, descriptions, and features from Ic-phoenix technical data files:  

### **Manufacturer:**  
- **HEIMANN Sensor GmbH** (a company specializing in infrared sensors and thermal imaging solutions).  

### **Specifications:**  
- **Type:** Thermopile infrared (IR) sensor  
- **Spectral Range:** 5.5 µm to 14 µm (optimized for human body temperature detection)  
- **Field of View (FOV):** ~ 100°  
- **Temperature Measurement Range:** Typically 0°C to 50°C (may vary based on calibration)  
- **Output Signal:** Analog voltage or digital (depending on configuration)  
- **Supply Voltage:** Typically 3V to 5V DC  
- **Response Time:** Fast (milliseconds range)  
- **Package Type:** TO-39 metal can (common for thermopile sensors)  

### **Descriptions & Features:**  
- **Non-Contact Temperature Sensing:** Detects infrared radiation emitted by objects (e.g., human body temperature).  
- **High Sensitivity:** Optimized for detecting small temperature differences.  
- **Integrated Thermistor:** Provides ambient temperature compensation for accurate readings.  
- **Compact & Robust Design:** Suitable for embedded applications (e.g., medical thermometers, HVAC systems).  
- **Low Power Consumption:** Ideal for battery-operated devices.  
- **Calibration Required:** Factory or user calibration needed for precise measurements.  

This sensor is commonly used in applications such as **fever detection systems, industrial thermometers, and smart home devices**.
