Features and Construction
The WiFi node module combines sensor technology with wireless connectivity in a compact package designed for integration into monitoring systems and smart devices. This section examines the module's construction and operational characteristics based on the available specifications.
Material and Build
The module incorporates electronic components including the DHT11 temperature and humidity sensor on a circuit board designed for reliable operation within specified measurement ranges. The power module components are configured to accept DC voltage inputs from 3.7V to 12V, providing compatibility with various power sources including battery setups. The construction focuses on functional electronic components rather than decorative housing, making it suitable for integration into larger systems or custom enclosures.
Size and Practical Fit
With dimensions of 25mm by 21mm and a weight of 3.8g, the module occupies minimal space when integrated into electronic projects or IoT devices. This compact form factor allows for installation in constrained locations while maintaining full sensor functionality. The small footprint makes it particularly suitable for DIY electronics projects where component space is limited or for integration into existing devices without requiring significant redesign of housing or mounting arrangements.
Uses and Placement
The WiFi node module serves multiple monitoring applications through its temperature and humidity sensing capabilities combined with wireless data transmission. Understanding its operational parameters helps determine suitable placement and integration approaches.
Event or Professional Use
For professional monitoring applications, the module's DHT11 sensor provides temperature readings from 0°C to 50°C and humidity measurements from 20% to 90% relative humidity, covering typical indoor environment ranges. The WiFi connectivity enables integration into larger monitoring networks where multiple sensors transmit data to central collection points. This allows for distributed environment monitoring across different areas or rooms without requiring extensive wiring infrastructure between sensor locations and data collection systems.
Everyday Home Use
In residential settings, the module offers practical temperature and humidity monitoring for areas where environmental conditions matter, such as living spaces, utility rooms, or storage areas. The wireless operation eliminates the need for running cables through living areas, while the support for battery power enables placement in locations without convenient power outlets. Home users can monitor conditions remotely via connected devices, receiving updates on temperature and humidity levels without needing to physically check different areas of the property.
