Gelidus Research Presence Sensor 1 (GRPS1)
Device Type: sensorElectrical Standard: usBoard: esp32
GRPS1 Device Info
The Gelidus Research PS1 supports either the LD2420 or LD2410C HLK 24Mhz Radar Module.
- Compact 40 x 80 mm PCB
- 4 Pin ESP programming header (3.3v only)
- Powerful ESP32S Dual Core 240Mhz 4MB Flash, BLE and WiFi module
- Dual core ESP32S enables simultaneous Wifi and BLE radios for optional BLE tracking
- 5 Pin HLK-LD2420 socket populated with an HLK-LD2420
- Also supports an LD2410C with JP1 set at 5 Volts.
- Powered directly with US AC plug receptacle blades (110-240 VAC)
- Designed to insert into a 3D printed protective Radome housing.
