Remote Temperature Monitoring Systems
ControlByWeb’s temperature modules provide an accurate way to remotely monitor temperatures over an IP network. WiFi temperature sensors and Ethernet temperature sensors are both available depending on your project needs. The modules can be used for environmental temperature monitoring systems and simple control. Multiple temperature sensors can be connected, and certain models also have relays that can be used for control.
Our temperature modules are fully configured in minutes using a web browser. There is no monthly subscription, and no additional software needed.
Our one-wire compatible controllers can be used with our sensors when looking for temperature and humidity control or a similar solution.
Setup Temperature Alert Emails
Configure the modules to send email messages when a preset temperature is reached.
Log Temperature Data
Log temperature data over time and send log files via email or FTP at preset intervals.
Control Relays Based on Temperature Sensor Data
Our temperature modules provide remote temperature monitoring and remote relay control using a standard web browser. These relays can control devices such as alarm signals, heaters, fans, etc.
Send Temperature Data via API
ControlByWeb’s temperature monitoring modules can easily send sensor data to third-party software, control systems, or PLCs using XML or Modbus TCP/IP.
