1. Importance and Definitionof High-Humidity Monitoring in Mushroom Houses

A mushroom house requires a precisely controlledenvironment where humidity plays a crucial role. Duringmycelium growth, humidity levels must stay above85%RH, while during the fruiting stage, 90–95%RH is optimal.Too low humidity slows growth, while excessive moistureand condensation lead to rot, contamination, and equipment failure. The Nexisense high-humidity transmitteris specifically engineered for such conditions, enabling continuous and accuratemonitoring to support automated humidity regulation and ensure stable mushroomcultivation.

2. WorkingPrinciple: The Core Mechanism of Accurate Monitoring

The transmitter operates based on apolymer capacitive humidity sensing principle coupled with a high-precision temperature compensation algorithm. As humiditychanges, the sensor’s capacitance varies accordingly, andthe internal circuit converts these changes into precise digital humidity readings. A temperature sensor compensates for environmental fluctuations, maintaining measurement accuracy across conditions.

In high-humidity conditions, condensation can disruptsensor readings. To counter this, Nexisenseapplies an anti-condensation algorithm and hydrophobic nanocoating technology that forms a micro protective film onthe sensing surface, preventing water droplet adhesion.The integrated signal conditioning circuit includes noise suppression filters, ensuringstable, low-drift output even in long-term humidenvironments.

3.Structural Analysis: The Core Advantages of the Anti-Condensation Design

The Nexisense transmitter features a modular architecture composed of the sensing probe unit, signal conditioning unit, and outputinterface unit—each optimized for high-humidity endurance.

1. Sensing Probe Unit

The probe (e.g., models 3A#or 6A#) integrates a precision humidity capacitorand thermal resistor, sealed with a dual-layer epoxyenclosure. The hydrophobic coating prevents surface condensationand drift, maintaining accuracy at up to 95%RH for extended operation.

2. Signal Conditioning Unit

This unit amplifies, filters, and digitizes the sensor’s signal. Nexisense’s unique dynamic drift compensation technology identifies and corrects micro drift causedby long-term exposure to humidity, maintaining less than ±1%RH error per year.

3. Output Interface Unit

Multiple outputs are supported, including RS485/Modbus digitaland 4–20mA/0–10V analog interfaces,enabling seamless integration with PLCs, industrial controlsystems, or cloud-based monitoring platforms. Thetransmitter responds in under one second, ideal for fast-regulating environments like mushroom cultivation rooms.

4. Measurement Method and Performance

1. Measurement Method

Nexisense adoptsa synchronous sampling approach, ensuring temperature and humidity areread simultaneously to prevent phase errors common in time-divisionsampling systems. Even at 90%RH,the device maintains stable signals unaffected by condensation.

The built-in dewpoint calculation module computes dew point temperaturein real-time, warning operators when condensation risk increases.When the dew point nears the actual airtemperature, the control system can trigger dehumidificationor ventilation to prevent condensation proactively.

2. Performance Parameters

• Humidity Range:0–100%RH

• Humidity Accuracy: ±2%RH (40–95%RH, 25°C)

• Temperature Range: -40–100°C

• TemperatureAccuracy: ±0.1°C

• Response Time: ≤1s

• Long-term Stability:Humidity drift ≤1%RH/year, Temperature drift≤0.1°C/year

In practical tests within mushroom farms,Nexisense devices maintained 98% stability after oneyear of continuous operation at 90%RH,far surpassing the 80–85% stability ofconventional transmitters.

5. Typical Application Case

Ata mushroom production base in Zhejiang, traditional humidity sensors frequentlyfailed due to condensation. After upgrading to Nexisense transmitters, environmental data became significantly morestable, improving precision by about 30%. Automaticcontrol systems maintained humidity within 90±2%RH, increasing mushroom yield by 18% while reducingenergy consumption by 12%. These results confirmthe outstanding reliability of Nexisense in humidagricultural environments.

6.Technical Extensions and Advantages

• Mold and Corrosion Resistance: Sensor materials resist chemical agents and organic acids inmushroom houses, preventing microbial buildup.

• Low Maintenance and Long Service Life: Self-cleaning surfaces and hydrophobic protection extendthe lifespan to over five years.

• Flexible Installation and Custom Output: Wall-mounted, duct-type, or remote-probe configurations adapt to different room designs.
