High Temp Humidity Sensor
About high temp humidity sensor
Where to Find High Temp Humidity Sensor Suppliers?
China remains the central hub for high temp humidity sensor manufacturing, with key production clusters in Shenzhen, Huizhou, and Dalian enabling specialized capabilities in environmental sensing technology. These regions host vertically integrated supply chains that support rapid prototyping and scalable production of digital temperature and humidity sensors capable of operating under extreme conditions—typically up to 125°C and 95% RH.
Manufacturers in Shenzhen and Huizhou leverage proximity to semiconductor foundries and PCB assembly facilities, reducing component lead times by 15–25% compared to offshore alternatives. Dalian-based suppliers focus on industrial-grade environmental monitoring systems, integrating advanced calibration techniques for long-term stability in harsh environments such as cold chain logistics, cleanrooms, and HVAC systems. The regional ecosystem supports full-cycle development—from sensor module design to cloud-connected data logging platforms—enabling OEMs and system integrators to streamline product deployment.
Suppliers typically operate automated SMT lines and environmental test chambers for burn-in validation, ensuring consistent performance across batches. Average production capacity ranges from 50,000 to 200,000 units per month depending on model complexity, with fast-turnaround sampling available within 7–14 days for standard configurations.
How to Choose High Temp Humidity Sensor Suppliers?
Effective supplier evaluation requires a structured approach focused on technical capability, quality assurance, and transaction reliability:
Technical & Functional Compliance
Verify sensor specifications align with application requirements, including operating range (e.g., -40°C to +125°C), accuracy (±1.5% RH / ±0.3°C typical), and output protocols (I2C, RS485, analog, or wireless). Confirm compatibility with industrial communication standards such as Modbus TCP or MQTT for integration into SCADA and IoT platforms. For critical applications, demand evidence of long-term drift testing and thermal hysteresis compensation.
Quality Management Systems
Prioritize suppliers with documented adherence to ISO 9001 standards and component-level certifications such as RoHS and REACH. While not always explicitly stated, leading manufacturers implement AEC-Q100-inspired stress testing for passive components and perform batch-level calibration using NIST-traceable reference instruments. Request access to test reports covering linearity, repeatability, and response time under sustained high-temperature, high-humidity conditions.
Production and Customization Capability
Assess scalability through facility size and equipment depth:
- Minimum monthly output capacity of 50,000 units for volume procurement
- In-house firmware development and configuration software tools
- Support for custom packaging, labeling, and branding (including LCD display options and SIM card integration)
- Ability to modify housing materials for chemical or UV resistance in aggressive environments
Cross-reference claimed capabilities with actual order fulfillment metrics such as on-time delivery rates (>97% recommended) and reorder frequency.
Transaction and Risk Mitigation
Utilize secure payment frameworks that link disbursements to verified shipment and inspection milestones. Analyze supplier responsiveness (target ≤3 hours) and historical performance indicators including reorder rate and dispute resolution history. Pre-production sampling is critical—test units under real-world conditions before committing to bulk orders, particularly when deploying in regulated sectors like pharmaceuticals or food storage.

Performance Analysis
Tzone Digital stands out with the highest reorder rate (20%) and extensive customization capabilities, supporting end-to-end integration including cloud platforms and mobile apps. Dalian Endeavour and Huizhou Sensor Tech achieve perfect on-time delivery records (100%), indicating strong operational discipline despite lower revenue volumes. Shenzhen Qinda offers competitive pricing and industrial-grade RS485-enabled transmitters suitable for building automation systems. Huizhou Sensor Tech provides the lowest per-unit pricing, making it ideal for high-volume buyers requiring cost-effective SHT-series sensor modules.
While most suppliers offer MOQs of 1–10 units for sampling, bulk pricing becomes advantageous at 100+ units. Buyers should prioritize partners with sub-3-hour response times and proven experience in export documentation for seamless customs clearance. For mission-critical deployments, verify calibration procedures and request lot-specific test data prior to acceptance.
FAQs
How to verify high temp humidity sensor supplier reliability?
Cross-check declared certifications with official databases. Request factory audit reports or video walkthroughs of production and testing areas. Evaluate technical responsiveness during inquiry phases—suppliers able to provide datasheets, pinouts, and communication protocols promptly demonstrate stronger engineering support.
What is the average sampling timeline?
Standard samples are typically shipped within 5–10 business days. Configurations requiring firmware adjustments or custom enclosures may take 15–20 days. Air freight adds 3–7 days for international delivery.
Can suppliers integrate sensors into existing monitoring systems?
Yes, many suppliers support protocol-level integration via I2C, UART, or RS485 interfaces. Some offer preconfigured gateways and cloud platforms with API access for real-time data integration into third-party dashboards or enterprise resource planning (ERP) systems.
Do manufacturers provide free samples?
Free sample policies vary. Most suppliers charge nominal fees (covering 30–50% of unit cost) refundable against future orders. Full waivers are common only after establishing purchase intent above 1,000 units.
How to initiate customization requests?
Submit detailed specifications including operating environment, required accuracy, power supply voltage, output signal type, housing material preferences, and communication protocol. Leading suppliers will respond with technical feasibility assessments, schematics, and prototype timelines within 72 hours.
