Frequently Asked Questions
Everything you need to know about Yoctopuce USB sensors and SMSEagle SMS gateways
💬 What is a Yoctopuce USB sensor?
A Yoctopuce USB sensor is a plug-and-play measurement module that connects directly via USB to a PC, server, or network hub. It requires no driver installation: it is natively recognized by Windows, macOS, and Linux. Each module includes a built-in web server and an API available in Python, JavaScript, C++, C#, Java, PHP, and many other languages.
💬 Do Yoctopuce modules require driver installation?
No. Yoctopuce modules are driverless. They use the standard HID protocol and are instantly recognized by all operating systems: Windows, macOS, Linux, and even ARM-based systems like Raspberry Pi.
💬 How to measure temperature with a USB sensor?
Sensor Factory offers several Yoctopuce USB temperature sensors: the Yocto-Temperature (thermocouple), Yocto-PT100 (high-precision platinum probe), Yocto-Thermistor-C (thermistor), and Yocto-Meteo-V2 (temperature + humidity + pressure). Simply plug the module via USB, then read values through the built-in API, the integrated web page, or monitoring software (PRTG, Zabbix, etc.).
💬 Can Yoctopuce sensors work over a network (Ethernet, WiFi, GSM)?
Yes. Using YoctoHub-Ethernet, YoctoHub-Wireless, and YoctoHub-GSM, any Yoctopuce USB sensor can be deployed on an IP network. The hub exposes sensors via an HTTP/REST API identical to direct USB connection. This is ideal for remote monitoring of server rooms, warehouses, or industrial sites.
💬 Do Yoctopuce modules have a built-in datalogger?
Yes. Most Yoctopuce sensors include an internal datalogger that automatically records measurements in flash memory. Data is timestamped and accessible even after USB disconnection. Capacity varies by model, from a few hours to several weeks of measurements.
💬 What is an SMSEagle SMS gateway?
An SMSEagle SMS gateway is a hardware device that enables sending and receiving SMS from any application via an HTTP/REST API. Unlike cloud SMS services, SMSEagle operates with a local SIM card: no SaaS subscription, no third-party dependency, and full control over your data.
💬 What is an SMS modem used for in business?
An SMS modem like SMSEagle is primarily used for: sending IT monitoring alerts (Nagios, Zabbix, PRTG), notifying about outages or incidents, sending bulk SMS for internal communication, and implementing two-factor authentication (2FA). It integrates via a simple REST API or email-to-SMS.
💬 How to choose between SMSEagle NXS-9750-4G and NXS-9700-4G?
The NXS-9750-4G is the high-end model with a rack-mountable metal enclosure, dual SIM slots, and a more powerful processor for high SMS volumes. The NXS-9700-4G is the standard compact model with a single SIM slot. For typical IT monitoring use (a few hundred SMS per day), the NXS-9700-4G is more than sufficient.
💬 What programming languages are compatible with Yoctopuce sensors?
Yoctopuce modules provide official libraries for: Python, JavaScript/Node.js, C++, C#/.NET, Java, PHP, Delphi, Visual Basic, Objective-C, and TypeScript. A command-line API is also available. All libraries are open source and downloadable from yoctopuce.com.
💬 Does Sensor Factory ship outside of France?
Yes. Sensor Factory delivers throughout Europe. Shipping is free within mainland France for orders over EUR 1,500 (excl. tax). For other European countries, shipping costs are calculated at checkout. Technical support is available in French and English, Monday to Friday.
💬 Can Yoctopuce sensors be used for server room monitoring?
Yes, this is one of the most common use cases. Yocto-Meteo-V2 (temperature, humidity, pressure), Yocto-Volt, Yocto-Amp, and Yocto-Watt modules enable monitoring the physical environment of a data center. Combined with a YoctoHub-Ethernet, they feed measurements directly into monitoring tools like PRTG, Zabbix, Centreon, or Nagios via SNMP, HTTP, or custom scripts.
💬 What are the advantages of USB sensors over wireless IoT sensors?
Yoctopuce USB sensors offer several advantages: no batteries to replace (USB-powered), no network configuration needed, higher accuracy than consumer wireless sensors, near-zero latency, and comprehensive APIs for integration. They are particularly suited for professional environments where reliability and ease of integration are top priorities.
