1591.2 Prerequisites

Before diving into this chapter, you should be familiar with:

1591.3 Introduction

Industrial IoT and wearable health monitoring represent specialized domains with stringent requirements. Industrial kits must handle harsh environments, industrial protocols, and safety certifications. Wearable health kits require medical-grade sensors, validated algorithms, and consideration of regulatory pathways. This chapter explores leading platforms in both domains.

Industrial IoT Kits work in factories and harsh environments. They typically include: - Wide temperature range (-20°C to +60°C) - Industrial voltages (24V inputs) - Protocol support (Modbus, BACnet, OPC UA) - DIN rail mounting for industrial enclosures

Wearable Health Kits monitor body signals. They typically include: - Medical-grade sensors (heart rate, SpO2) - Small form factor for body-worn use - Low power for all-day battery life - Validated algorithms for accuracy

Example: Arduino Opta controls factory relays using Modbus. Maxim Health Platform measures heart rate with FDA-quality sensors.
