Ultrasonic + WiFi + Solar: How HojellyTek TLC2326-WF-S Redefines Outdoor Level Monitoring

Target Audience: Engineering Procurement, System Integrators, Technical Decision Makers
I. Product Overview

The HojellyTek TLC2326-WF-S is a smart WiFi ultrasonic level sensor designed for outdoor water tanks and oil tank level monitoring. It utilizes non-contact ultrasonic measurement technology, enables remote monitoring through the Tuya/Smart Life platform, and supports dual power supply options (solar charging + mains power), thoroughly solving the power and signal coverage challenges of outdoor level monitoring.

II. Core Advantages Explained

Advantage #1: Ultrasonic Non-Contact Measurement – Never Clog, Maintenance-Free

Unlike traditional float-type or submersible level sensors, the TLC2326-WF-S uses ultrasonic non-contact measurement. The sensor is installed at the top of the tank, emitting ultrasonic pulses toward the liquid surface and calculating level height by measuring echo time.

Key benefits:

• No liquid contact: Sensor never corrodes or gets contaminated
• No moving parts: No float jamming, spring fatigue failures
• Wide media compatibility: Water, oil, mild acids/alkalis, sewage all measurable
• Maintenance-free: Virtually no daily maintenance required after installation

Industry selection guidelines clearly state: For media containing impurities or foam, non-contact ultrasonic sensors should be prioritized. The TLC2326-WF-S is the best practice for this selection principle.

Advantage #2: Solar Charging + 18650 Battery – Perfect Solution for Outdoor No-Power Locations

The biggest installation challenge for outdoor tanks and rooftop water towers is power supply. Traditional level monitoring equipment requires running power lines outdoors, which is costly and poses safety risks.
The TLC2326-WF-S offers dual power options:

• Solar panel power: 3.3W 5V solar panel, sufficient for daily operation
• 18650 rechargeable battery: Energy storage for seamless transition on cloudy/rainy days
• Power adapter: For locations with mains power available

This means:

• No dedicated wiring for level monitoring
• Installation location not limited by power availability – works with sunlight
• Fully automatic solar charging, no manual battery replacement required

Advantage #3: IP67 Waterproof + Wide Temperature Range – Built for Outdoor Environments

Rooftop water tanks and outdoor oil tanks are exposed to sun, rain, heat, and cold year-round. Devices with insufficient protection ratings can experience housing aging and water ingress failures within months.

The TLC2326-WF-S protection features:

CE/RoHS/REACH certified – Complies with international safety and environmental standards

IP67 waterproof rating – Completely dustproof, can be temporarily submerged (1m for 30 minutes)

Wide operating temperature – -10℃ to +70℃, suitable for most climates
Industry reviews explicitly warn: "Don't choose models without waterproofing or weak signal – prioritize IP68 protection + LoRa/4G dual mode". While the TLC2326-WF-S is IP67-rated, this is fully sufficient for rooftop tank rain exposure, and the WiFi solution offers better cost-effectiveness in areas with good signal coverage.

Advantage #4: Deep Tuya Platform Integration – Global Access, Multi-Device Control

The TLC2326-WF-S seamlessly integrates with the Tuya/Smart Life platform, one of the world's largest smart home ecosystems:

• Real-time mobile App view: Liquid level percentage, battery level, signal strength all visible
• Multi-user sharing: Share with family, property managers, maintenance personnel
• Multi-device management: Manage multiple sensors with one account – supports up to 100 sensors simultaneously
• Cross-platform compatibility: Data syncs to Alexa, Google Home, and third-party platforms

Compared to products with proprietary protocols, the Tuya platform ecosystem advantage is significant – no additional gateway purchase required, direct integration with existing smart home systems.

Advantage #5: Simple Installation – Nut Mounting, Ready to Use

The product design fully considers ease of installation:

3m sensor cable: Separate sensor and main unit design for flexible signal reception

Nut mounting: Fix sensor to tank top using included nut (requires pre-drilled opening or DIY drilling)
2m solar panel cable: Position solar panel for optimal sunlight exposure

No professional tools required: Basic screwdriver sufficient

Compared to submersible sensors requiring wall penetration wiring or float sensors requiring drilling and sealing, the TLC2326-WF-S significantly reduces installation complexity
