INFINITY ENERGY: The Future Of Self-Powered IoT
Power remains the quiet obstacle slowing the global expansion of wearable and IoT devices. Despite rapid technological progress, these devices continue to depend on batteries that fail, leak, or require replacement, ultimately adding to e-waste within a few years. Thankfully, the idea of everyday devices such as TV remotes, fitness bands, smart switches, sensors, or even medical patches operating indefinitely without a battery is becoming increasingly feasible.

Multifunction Human Detection And WEATHER MONITORING SYSTEM
A human detection system was designed earlier to utilise the microwave Doppler effect to detect human movement and trigger AC appliances such as light bulbs and other electrical loads up to 1A. The design incorporated a solder jumper pad for mode selection, enabling the same PCB to be configured for IoT compatibility by integrating IoT functionality into the radar switch. This configuration supports real-time radar data monitoring, alert reception, and wireless control of lights over a WiFi network.

Miniature IoT WATER TDS And LEVEL MONITOR Cum CONTROLLER
For setups that rely on stored water, clear awareness of tank level and water quality is essential. Traditional level monitors are often bulky offline devices with only simple LED indicators, while many newer smart models can be expensive and still ignore key quality parameters such as total dissolved solids (TDS) and turbidity. As environmental contamination increases, continuous monitoring of both water level and purity has become necessary.

Multi-Use RF RELAY CONTROL SYSTEM
The demand for convenient and reliable switching systems is increasing across homes, offices, and industrial environments. Conventional methods, such as wired switches and infrared (IR) remotes, have clear limitations: wired systems require complex installation and lack mobility, while IR control is effective only over short distances and requires a direct line of sight. Radio frequency (RF) technology overcomes these constraints by enabling longer-range, robust wireless communication, making it well-suited for automation.

SUPERIOR MOTION SENSOR Using Microwave Doppler Radar
An earlier design introduced a touch solid-state AC switch. The new version advances this concept with a sophisticated human radar sensing system that can also be configured for IoT and smart automation. The system uses 70 per cent Indian components and is entirely Indian-engineered. At its core lies a microwave doppler radar sensor that detects human motion with far greater reliability than traditional PIR or IR-based systems. Unlike PIR sensors that depend on heat signatures and often malfunction under sunlight, near heaters, or behind curtains, the microwave radar delivers superior penetration through nonmetallic barriers, immunity to heat-induced false triggers, reduced sensitivity to small animals, and omnidirectional detection without requiring a direct line of sight.
