Convergent Smart Technologies (Abbreviation: CST) is a Singaporean SME start-up that developed a Smart Toilet System for a maintenance free technology that mainly consists of People Density Counter and Ammonia Sensor. Data collected with analytics provide predictive cleaning and inventory usage. This technology improves productivity of restroom and building cleaning companies.

Invention
The system, initially developed by engineers from Singapore's Agency for Science, Technology and Research, uses sensors to assess the levels of ammonia - present in urine - as well as hydrogen sulphide, which is found in faeces. The system then alerts maintenance staff as to when the toilets are likely to need cleaning. Institute for Infocomm Research (I2R) licensed the technology to Convergent Smart Technologies to scale for the mass market.

Customers
A sizable number of places have installed the Smart Toilet System, including hotels such as The Fullerton Hotel and the Marina Bay Sands, real estate companies like Frasers Centrepoint Malls, CapitaLand and Far East Organization, food centers in Tiong Bahru, Maxwell and Serangoon Gardens and tourist spots such as Singapore Zoo and River Safari.

Six toilets inside The Shoppes at Marina Bay Sands, installed with Convergent Smart Toilet System, have became the first batch to garner the highest six-star rating from the Restroom Association (Singapore) or RAS since the rating band was introduced in 2015. The restrooms are equipped with sensors to track the level of ammonia, which rises as these facilities become dirtier. When the ammonia level hits a certain level, an alert is sent via text message to activate a cleaner. The system also monitors visitor volume, which can be used to estimate when amenities such as hand soap or toilet paper is running out.
