The Senhus Detect series is an advanced human presence sensor utilizing the ESP32 microcontroller and the LD2410 radar module. Senhus Detect is created with size in mind. It is perfect for various home automation applications, seamlessly integrating with Home Assistant to enhance your smart home setup.
Specifications
Microcontroller: ESP32-C3 (SG-1C) or ESP32-S3(SG-1S)
Radar Module: LD2410C
Detection range: depends on placement, sensitivity and installed radar firmware. The original guides disagree about detection distance. Gate numbers are settings, not metres, and are not a guaranteed detection range. Test both moving and seated occupants in the intended room before relying on an automation.
Field of View: 120 degrees
Power Supply: 5V DC (via USB-C)
Communication Protocols: Wi-Fi, Bluetooth
Dimensions in mm: W27 x H23 x D15
Ideas for Automations
The LD2410C radar module in Detect series provides exceptional configuration and detection capabilities:
High Sensitivity: Detects minor movements, ensuring accurate presence detection.
Distance-gate tuning: Set separate movement and still-presence thresholds for radar gates 0–8. Gate numbers are not metres; see Configuration.
Automatic Lighting
Automatically turn on lights when human presence is detected and turn them off when no presence is detected for a specified period.
HVAC Control
Integrate your HVAC system to adjust the temperature based on occupancy, ensuring energy efficiency and comfort.
Security Enhancement
Detect human presence in your home and trigger alerts, cameras, or alarms.
Smart Bed Setup
Place the sensor under the bed to monitor presence and movement, triggering actions like adjusting the room temperature, playing soothing music, or turning off lights when you go to bed.
