IoT base component

All of our IoT devices have reliable hardware developed in-house as the basis for developing the various actuators and sensors.

Network

• Connection via WLAN - WIFI 2.4G ~ 2.5G (2400M ~ 2483.5M) 802.11 b/g/n/e/i
• Meets FCC, CE, TELEC, SRRC standards

Connections

• Connection for 4 buttons with protective circuit (IEC 61000-4-2 ESD Protection (Level 4), ± 8-kV Contact Discharge, ± 15-kV Air-Gap Discharge) - with wake-up function from sleep mode
• Connection for 4 digital sources - with wake-up function from sleep mode
• Connection for 2 analog sources

Signal transmitter

• Multi-colored LED for visual status messages: blue "in progress", green "ok", red "error" (can be switched off)
• Beeper for acoustic notification of status or error messages (can be switched off)

Power supply

• Power supply via USB and / or battery (Li-Ion) with automatic switching and battery trickle charging
• Intelligent charging circuit with various protective circuits (500mA USB Input Current Limit, Inrush Current Limiter, Precharge and Fast-Charge Safety Timers, Termination Current, Reverse Current, Short-Circuit, Thermal Protection)
• Two Li-ION battery options: 18650 (∅18mm, length 650mm) or the smaller variant 18350 (∅18mm, length 350mm)
• 3.3V voltage regulator: up to 96% efficiency, buck-boost (use of the full battery capacity), switch-off at 3.15V (to protect the battery), overtemperature protection
• Reliable, stable and vibration-proof battery holder thanks to spring-loaded clamps

Energy management

• Long runtime thanks to extremely energy-saving (0.02mA / 20µA) operation with the 3.3V voltage regulator switched off in sleep mode (waiting for the next action or safety timer)

Safety features

• Configurable control interval (safety timer) for self-diagnosis: battery level, WLAN connectivity, etc.
• Complies with RoHS 2 (Directive 2011/65 / EU)

Configuration

Our IoT devices can be extensively configured to easily find space in the existing infrastructure.

• Our IoT devices can be extensively configured to easily find space in the existing infrastructure.
• Definition of different WLAN accesses (main access and alternatives in the event of failure)
• Any definition of the protocols / parameters / URLs that are to be called when an action has been triggered or a sensor result is available
• Comprehensive configuration of different times / intervals (e.g. measuring temperature every 5 minutes)
• Definition of the acoustic signals or deactivation

Using this IoT basic component, we offer the following components:
IoT action/feedback button
IoT temperature/humidity
IoT guardian "Heimdall"
