24/7 Water Quality Monitoring
Automated 288 Readings Daily
Direct-in-water autonomous monitoring stations built for precision aquaculture. Purpose-engineered for two primary operational domains: Farmext Envisor Shrimp (intensive & super-intensive shrimp farming) and Farmext Envisor Marine (open-sea net pens, bays & offshore cages). Continuous testing for Dissolved Oxygen (DO), pH, Temperature, and Salinity every 5 minutes, powered by solar energy with patented self-cleaning optical sensors.
Shrimp & Marine
2 Dedicated Editions for Distinct Aquaculture Environments
Pond ecosystems and open marine waters present starkly contrasting challenges in biofouling, salinity ranges, and mechanical forces. Tep Bac developed two dedicated Envisor platforms engineered for pinpoint precision and long-term durability.
Farmext Envisor Shrimp
Optimized for whiteleg shrimp and black tiger shrimp intensive & super-intensive operations (HDPE-lined ponds, earthen ponds, RAS recycling facilities).
Farmext Envisor Marine
Engineered for open-ocean net pens, coastal fish cages, and marine bays (cobia, Asian seabass, pompano, spiny lobster, marine mollusks).
Farmext Envisor Marine: Engineered for the Open Sea
Open-sea net pens and deep marine bays demand total resistance against saltwater corrosion, violent swell dynamics, and zero reliance on onshore power cables. See how Envisor Marine is manufactured and deployed on commercial cages.
Offshore Net Pens
Up to 12m Depth
Deep-Water Cage Quality Monitoring for Marine Fish & Lobster
Securely clamped to circular HDPE floating collars. A Kevlar-reinforced umbilical drops the multi-sensor cluster down to 12 meters, continuously sampling DO, salinity, and temperature where commercial fish actually dwell.
Field Deployment
Modular Raft Clamping
Rugged Mechanical Fixation β’ Zero Power Cables Required
Engineered universal mounting brackets attach directly to HDPE cage pipes or wooden rafts without structural alteration. 100% powered by an integrated high-efficiency solar panel and a 20,000mAh Lithium cell.
Industrial Scale
Australis Aquaculture
Trusted by Commercial Marine Aquaculture Leaders
Dozens of Envisor Marine stations assembled and calibrated under rigorous quality control standards, deployed by leading industrial marine producers such as Australis Aquaculture in high-energy sea waters.
IP68 Enclosure
4-Day Offline Buffer
IP68 Rated Enclosure β’ Unbreakable Salt-Mist Data Resiliency
Hermetically sealed ABS junction box with compression cable glands. When stormy sea weather disrupts cellular service, onboard flash memory records up to 4 days of data, auto-syncing with Farmext App the moment signal is re-established.
How Many Manual Tests a Day Is Truly Enough?
In intensive shrimp ponds and offshore cages, water parameters shift hourly. Conventional manual sampling leaves perilous data blind spots that can wipe out entire crops overnight.
Nighttime Dissolved Oxygen Crashes
While algae produce oxygen during the day, nighttime turns the entire pond biomass into oxygen consumers. DO can plummet from 7.0 mg/L to below 3.0 mg/L between 1:00 AM and 4:00 AM, triggering mass suffocation.
Manual Testing: Inconsistent & Infrequent
Testing once or twice a day with kits or handheld meters provides only isolated snapshots. In offshore cages, traveling during rough seas is dangerous, leaving farms completely blind for days.
Stationary Probes Blinded by Fouling
Shrimp pond sludge and marine barnacles foul standard immersion probes within days. Without automated self-cleaning, sensor optical windows get coated, reporting false readings.
3 Technological Breakthroughs of Farmext Envisor
Refined and proven over 5 years across hundreds of commercial aquaculture operations in Southeast Asia.
288 Tests Daily β’ Continuous Visibility
Sensors log data every 5 minutes and generate real-time trend charts. Farm managers immediately see whether DO is steadily rising or crashing downward.
- Zero manual testing labor
- Early warning for algae crashes
Automated Sensor Self-Cleaning
A mechanical wiper sweeps across optical sensor windows before every measurement, maintaining optical purity without the need to hoist and wash equipment by hand.
- Calibration stability for 6β12 months
- Prevents measurement drift
Solar Power & 72h Backup Battery
Integrated high-efficiency solar panel coupled with an industrial-grade Lithium battery pack. Functions completely autonomously in open waters for up to 3 consecutive overcast days.
- Zero shore cable costs
- 100% electrical safety on water
Built for the Brutal Realities of Water Environments
Constructed with UV-stabilized engineering polymers, salt-resistant composites, and marine-grade stainless hardware. Hydrodynamic buoyancy guarantees steady orientation in wave surges.
Offline Data Buffer
When cellular or Wi-Fi coverage drops, internal memory buffers up to 4 days of telemetry, automatically uploading to cloud upon reconnection.
Status LED & Power Key
Multi-color LED status indicators and a tactile power button make it simple for operators to confirm battery health and network link from distance.
IP68 Waterproofing
Central electronics and junction boxes meet IP68 waterproof standards, impervious to salt fog, heavy rainfall, and direct waves.
Optical DO Sensor
Luminescence quenching technology consumes zero oxygen during reading, eliminating the electrolyte maintenance required by old membrane sensors.
Automated Synergy: Envisor + Cabinet + App
Beyond monitoring, Envisor syncs with the Farmext Cabinet control unit to turn your farm into a responsive, self-operating ecosystem that protects crops 24/7.
Envisor Monitors
Measures bottom DO continuously every 5 minutes and compares against predefined threshold.
DO Drop Detected
When DO falls below 5.0 mg/L, an immediate automated command is transmitted via cloud.
Cabinet Auto-Starts
Farmext Cabinet closes contactors and engages paddlewheel aerators or bottom diffusers.
App Push Alert
Farm manager receives confirmation notification on smartphone; event is logged to electronic record.
Save 15% β 25% on Aeration Electricity Bills
Instead of running aerators blindly during daytime when algae already super-saturate the water with oxygen, aerators run strictly when required, reducing electricity consumption and mechanical wear.
