Wireless NH3 Ammonia Gas Sensor WS433-G4F-NH3

SKU: WSSFC-G4F-NH3

Doc No: WSSFC-G4F-NH3-DS-EN-10

Introduction

WSSFC-G4F-NH3 is a Wireless Sub-GHz sensor with a built-in advanced electrochemical gas sensor to measure Ammonia NH3 gas concentration with very high sensitivity for detecting the odor level in public toilets. The wireless portion is Sub-GHz technology from Texas Instruments allows long-range transmission at ultra-low power consumption. It will connect 2-way wirelessly to the wireless coordinator WS433-CL to send data and receiving the configuration. It can be configured the operation parameters like data sending interval, health check cycle...remotely from Globiots platform or via Modbus RTU software (thru the WS433-CL). Its default data rate is 50 kbps, which can be switched to 625 bps to increase the communication range. It can last up to 2-5 years with 2 AA batteries.
