Frequently Asked Technical & Sourcing Questions
Detailed technical specifications, ODM customization boundaries, firmware architectures, and factory compliance protocols answered by our chief hardware engineers.
What specific electrical valve types can your ODM irrigation controllers actuate?
1. Standard 24VAC Solenoids: Our primary commercial boards feature internal triac or optocoupled solid-state relays powered via external 120V/230V-to-24VAC step-down transformers, capable of sustaining 0.35A holding current and 1.0A inrush current per zone, compatible with Hunter, Rain Bird, Toro, and Irritrol commercial valves.
2. 9V-12V DC Latching Pulse Solenoids: Designed for solar or battery installations, these controllers use an H-bridge capacitive discharge circuit that outputs a 20ms to 50ms bipolar pulse to shift valve states, eliminating continuous coil heating and extending battery lifetime up to 3 years.
3. Motorized Ball Valves: Relay-switched 12VDC power outputs with limit switch feedback pins designed for high-flow agricultural trunk lines where pressure drops must be kept near zero.
How does the controller maintain scheduled watering routines during Wi-Fi or Internet outages?
Can Corunsmart flash custom proprietary firmware or open-source Tasmota / ESPHome onto production units?
• Tuya / Smart Life: Pre-provisioned with customer-owned Product IDs (PID), custom encryption keys, and white-label branded companion apps for iOS and Android.
• Matter-over-Thread / Wi-Fi: Certified Matter binaries with customized device attestation certificates (DAC) and vendor IDs (VID).
• Open-Source & Custom MQTT: ESP32 microcontrollers flashed with clean builds of Tasmota, ESPHome, or your proprietary C++/FreeRTOS firmware, locked down via Espressif Secure Boot V2 and Flash Encryption to protect your intellectual property.
What certifications and laboratory testing support do you provide for new ODM product introductions?
• Safety & Electrical: UL 1951, CSA C22.2, EN 60730-1, CE Low Voltage Directive (LVD).
• RF & Telecom: FCC Part 15C (USA), IC RSS-247 (Canada), RED Directive (Europe), Anatel (Brazil), and RCM (Australia/NZ).
• Environmental & Ingress: IP65/IP66/IP68 water ingress validation, salt spray chamber testing (ASTM B117), and UV accelerated weathering (ASTM G154).
• Water Efficiency: Algorithmic audits against EPA WaterSense specification standards for weather-based irrigation controllers.
What is your minimum order quantity (MOQ) and production turnaround for custom ODM hardware tooling?
• Phase 1 (Tooling & Mold Fabrication): 25 to 35 business days from 3D CAD sign-off to T1 plastic injection samples.
• Phase 2 (PCBA & Pre-Production Pilots): 10 to 14 days for surface mount setup and golden sample sign-off.
• Phase 3 (Mass Production): 30 calendar days for first production batches of 3,000 to 10,000 units.
How are flow sensors, rain sensors, and freeze alarms wired into the controller architecture?
• Pulse Flow Meters: A dedicated high-speed interrupt pin calculates liters/gallons per minute based on K-factor pulse frequency. If the flow rate exceeds or falls below user thresholds (indicating a burst pipe or stuck valve), the firmware automatically shuts down the corresponding zone and master valve.
• Rain/Freeze Sensors: Support for normally-closed (NC) and normally-open (NO) contact switches. When moisture expands internal cork discs or temperature drops below 3°C, the controller immediately suspends active watering sequences without requiring user intervention.
